SECTION I

GENERAL

This summary of changes to Section I of the ASME Code is not all inclusive and contains the
changes we consider most important to our clients. Please remember to use the Code for actual
requirements.

The 2011 Addenda to the Code become mandatory January 1, 2012. This addenda was printed on
white paper and was printed in its entirety. Also please note that Footnotes have been changed to
Endnotes and these endnotes are part of the Standard.

ASME will no longer issue addenda. The next edition of the Code will be issued in 2013 and then
issued every 2 years thereafter. Code Case Supplements will be published two times a year.
Interpretations will be posted on the ASME website at http://cstools.asme.org/Interpretations.cfm
in January and July of each year.

What ASME calls a “Special Notice” may be posted on the website prior to the 2013 Edition to
provide approved revisions to Code requirements. These revisions may be used upon issuance but
become mandatory 6 months after issuance. “Errata” to the Code will also be posted on the ASME
website to provide corrections. Errata are typographical or grammatical errors.

These “Special Notices” and “Errata” can be found at

SECTION I

GENERAL

The ASME is phasing out multiple stamps and moving to a single mark. The major driver
behind this change is to fully protect the marks. As the ASME needs to register marks in
the more than 100 countries in which stamped equipment is used, the use of a single mark
allows ASME to register one mark in these countries thus making it easier to afford greater
protection of a single mark rather than lesser protection for multiple marks.

The proposed schedule for implementing the move to a single ASME certification mark
will be publication in the 2011 Addenda to the Code. There will be a transition period
during which a Manufacturer or Constructor would be able to use either one of the 25
applicable current marks or the single mark. Use of the single mark would then become
mandatory on January 1, 2013. There will be a policy statement in the front of the ASME
Code books describing this transition period and an implementing Code Case in both the
BPV and Nuclear Code Case Books.

Each stamp holder must go to ASME’s CA connect (http://www.caconnect.asme.org),
establish an account if they have not already and request the new Mark. ASME will
not be sending individual notifications of this to the stamp holders – It is up to the
stamp holders to independently request this new mark

An example of how the stamping may appear In the case of Section I, the Designator that
will appear directly under the Certification Mark as “S”, “A" or “PP".

SECTION I, PART PG

PG-8.1.4.2

PG-67.7 was deleted in the 2009 Addenda. The reference in PG-8.4.1.2 to this paragraph
was deleted.

PG-13

Added CSA-G40.21 Grades 44W and 50W material to PG-13

PG-16.6

An action is being proposed to bring the Forewords of all BPV Sections up to date, and to
remove from the Forewords any paragraphs that embody rules, since it has been
determined that the Forewords are not “part of the Code” and cannot contain enforceable
rules.

Paragraph PG-16.6 was added to add the statement from the Forward addressing
tolerances. This was added here because many feel that Forwards are not a part of the
Code. Since the tolerance statement is mandatory language it was felt it needed to be
added to the body of the Code.

SECTION I, PART PG (Continued)

PG-22.1

The purpose of this item is to clarify the requirements of PG-22. The second sentence of
PG-22.1 contains the phrase “average stress” which is not defined in the Code and is used
generically in the literature thus being ambiguous. This proposal replaces the current
sentence with two sentences the first statement that Section I does not address stresses due
to additional loadings, and the second states that such loadings shall be addressed by the
Manufacturer based on engineering judgment and Code philosophy and points the user to
PG-16.1 for guidance

This paragraph was revised to say “This Section does not fully address additional loading
other than those from working pressure or static head. Consideration shall be given to such
additional loading. (See PG-16.1).” This replaced the second and third sentences in that
paragraph.

PG-27.4.4 Note 4

This paragraph was revised to indicate that e = 0 for “tubes strength-welded to tubesheets,
headers and drums. Strength-welded tubes shall comply with the minimum weld sizes of
PW-16.” This was revised to add tubesheets. Please note that “Strength Weld” referred to
here relates to a weld used to attach a tube and therefore the tube does not need expanding.
Weld Strength referred to in PW-15 refers to adequate weld strength to attach elements of
reinforcement.

PG-28

Section I up to this point did not address external pressure except for firetube boiler
furnaces in PFT-51 and manway openings in PG-28. This left out some items such as drum
heater coils. PG-28 has been revised to address cylindrical components under external
pressure by referring to PFT-51.4.

Summary of Changes

Added new title PG-28 COMPONENTS UNDER EXTERNAL PRESSURE

PG-28.1 THICKNESS OF CYLINDRICAL COMPONENTS UNDER
EXTERNAL PRESSURE
(PFT-50 paragraph has been revised and moved to PG-28.1)

PG-28.2WELDED ACCESS OR INSPECTION OPENINGS UNDER EXTERNAL
PRESSURE

PG-28.3 MAXIMUM ALLOWABLE EXTERNAL WORKING PRESSURE FOR
CYLINDRICAL COMPONENTS

(PFT-51 has been revised and moved to PG-28.3)

PG-31.2

The symbol for gasket moment is in PG-31.2 was different than in Figure PG-31.
Paragraph revised from hg to hG.

PG-32.1.4(a)

Revised to clarify intent

PG-33.1

The formula for A1 was revised to account for the fr factor. Up to this point, the formula
did not account for the situation where a weaker material was used for nozzles inserted into
the vessel wall. The term Wd was added as the width of the nozzle inserted into the vessel
wall beyond tn. Wd = not greater than the larger of D/2-tn or t (See Fig. PG33.2) Note, the
Wd applies to integrally reinforced nozzles per Fig UG-33.2.

Fig. PG-33.2

Revised to show Wd

PG-33.1, A-66 and A-69

Revised examples with regards to the addition of the term Wd.

PG-33.3

Revised the nomenclature for fr1 to be equal to Sn/Sv for all nozzles, not just those inserted
through the vessel wall. Also, an example problem in A-67 was corrected to square the
term WL3.

PG-49

Revised to limit the allowable stress for steam locomotives to 7500 psi to comply with the
Federal Railroad Administration.

PG-52.3

This paragraph was completely revised by deleting the present existing words and adding
rules to establish equivalent longitudinal efficiency for circumferential ligaments for use in
design formula of PG-27.2.2, A-125 and A-317. This clarifies that the designer can double
the circumferential efficiency to establish the equivalent longitudinal efficiency to use in
the design formula.

PG-52.5

Added “For all tube hole pattern arrangements, the equivalent longitudinal ligament
efficiency for any diagonal and circumferential ligaments shall be calculated and compared
to the longitudinal ligament efficiency. The lesser value of the longitudinal ligament
efficiency or the equivalent longitudinal ligament efficiency shall be used to calculate the
minimum required thickness and maximum allowable working pressure for the associated
cylindrical section.”

PG-52.6

Added “pc” for circumferential pitch Also, the reference to Fig PG-52.6 was incorrect
since there is no Fig PG-52.6. This reference was changed to PG-53.3

PG-60.1.6

Revised to add “A means of manually opening and closing the valves from the valve
operating floor or platform shall be provided.” This insures that gage glasses will be blown
down and done in a safe manner. Also editorially changed acceptance to acceptable.

PG-72.2

An editorial correct was made to the table in PG-72.2 by inserting the greater than symbol
in front of the number 70 in the second row. Also, references to A-300 were corrected to
reference A-301 and A-302.

PG-106.4.2

Deleted the word “steel” where it appears before the word “Economizer.”

PART PW

PW-28.2

Revised to say “volumetric NDE” instead of just radiography for welder qualifications to
bring Section I in line with the new Section IX allowing the use of UT.

PW-39

Revised to allow PWHT exemptions to be based only on nominal thickness as defined in
PW-39.3 and notes (a)(3), (a)(4), (a)6), (a)(8) through (a)(10), (a)(12) (a)(13), and (c) were
deleted and the remaining notes renumbered. Also please note, the reference to PW-34 in
note (a)(1) and (2) to table PW-39.1 should be PW-39.3.

PW-39.3

Revised to address cooling and heat up rates by reference to A-101. Also added definitions
of nominal thicknesses for different types of welds.

SECTION I, PART PW (Continued)

PW-40.3.4

Revised to allow the use of the temper bead technique as well as the half bead technique for
weld repairs after PWHT.

SECTION I., APPENDICES

A-65

Editorial changes to correct references to Figure PG-32 and making the correct reference to
PG-32.1.4.

A-68

Deleted the reference to Figure PG-32 and making the correct reference to PG-32.1.2 and
PG-32.1.4. Also adds the calculations for Dmas.

A-70

Editorial change to correct the calculation for A41 to show 0.3752 be multiplied by 1.

A-101

As reverenced in PW-39, this is a new non mandatory appendix giving suggested guidance
on heat up and cool down rates for PWHT.

A-317

Revised to address the weld strength question as shown in PG-27.

SECTION I, APPENDICES (Continued)

A-360

Revised as follows: B31.1 update to 2009 from the 2007 edition, Revised PTC-25 from
2001 to 2008, Revised SNT-TC-1A to the 2006 Edition and Revised note 4.

A-350

Changes the requirements for the AI to now to use their NB commission number and
endorsements even if the item is not registered with the NB.

A360

Revised Note 4 of Table A-360, to sztate: “The Manufacturer is cautioned that the O.D.
tolerance used to calculate the values for dimensions C shown in Table 1 and Table I-1
may be different from the tolerance listed in the applicable material specification and that
machining to this dimensions could result in a wall thickness (see PG-42.4.2), requiring
further action by the Manufacturer.”

DATA REPORT FORMS

The current requirements for recording an Authorized Inspector’s National Board
Commission and Endorsement on a Manufacturer’s Data Report (MDR) are:

If the item is National Board stamped, the commission number and endorsement must be
shown;
If the item is not National Board stamped, only the inspector’s state or province number
must be shown.

This is in conflict with the requirements of QAI-1 which requires the Inspector to have a
National Board Commission and Endorsement, yet the inspector may only record the
information if the item is National Board stamped.

Revise all Data Report Forms and Guides to instruct the Authorized Inspector to include
his/her National Board Commission Number and endorsement when signing all ASME
Data Report Forms.

SECTION IV, FORWARD

It became apparent that clarification was needed for establishing governing Code Edition
and Addenda for new construction and field assembly as well as for parts. Also, as a result
of initiating this item, CSP-9 (see background information file) was revised to establish a
policy for establishing the effective edition and addenda to be used to construct an item that
is to be stamped with an ASME certification mark (e.g. Code Symbol Stamp). The actions
proposed by this item are needed to implement that Policy.

Revise the Foreword, HG-100, Manufacturer’s Data Reports, and insert new mandatory
appendix 8 to address the requirements for governing Code edition.

SECTION IV, PART HG

HG-400.2(e)

The relief valve capacity exception found in paragraph. HG-400.2(e) for cast iron boilers
should also apply to cast aluminum boilers. The revision to this paragraph will accomplish
the intent.

For cast iron or cast aluminum boilers constructed to the requirements of Part HC or Part HA, the
minimum valve capacity shall be determined by the maximum output method.

HG-530.2

Some confusion was occurring with respect to proper name that should be shown on rating
plate as an Assembler with a Certificate to Install Nameplate only is not sufficiently
covered in the Code currently.

With the addition of the nameplate installation certificate the Section IV Committee
intended that the certificate holder was the one to assume responsibility for the boiler and
they would have their name on the nameplate.

Revise HG-530.2(c) to add new sub-paragraphs 1 and 2. New sub-paragraph HG-
530.2(c)(1)(a) and 530.2(c)(1)(b) will define a Shop Assembler as the certificate holder that
ultimately applies the ASME nameplate to the case iron or cast aluminum boiler. Sub-
paragraph HG-530.2(c)(2) will be sub-divided into HG-530.2(c)(2)(a) through HG-
530.2(c)(2)(d) and will incorporate the current requirements notes in HG-530.2(c)(1)
through HG-530.2(c)(4).

SECTION IV, PART HG (Continued)

HG-530.2 (Continued)

HG-530.2 Marking Requirements for Cast Iron or Cast Aluminum Boilers

(c) When the boiler size and number sections have been decided, the completed boiler shall
be marked with the Code Symbol shown in Fig. HG-530.1 and with the following data:
1) the Shop Assemblers name preceded by the words “Certified by”
2) maximum allowable working pressure
3) safety or safety relief valve capacity (minimum), as determined according to HG-
400.1(d) and Hg-400.2(e)
(4) maximum water temperature
(d) The Shop Assembler that is in possession of a Code Symbol Stamp and valid Certificate
of Authorization shall be one of the following:
(1) the shop that assembles sections into boilers, performs the hydrostatic test and
installs the nameplate.
(2) the shop that installs the nameplate on a boiler, previously assembled and hydrotested
by another authorized Certificate Holder.
(3) the shop that only installs the nameplate on a boiler jacket.

HG-502.3

At present, Section IV requires that the yield or tensile strength of a part burst tested be
determined from a specimen cut from the part tested from a location where the stress
during the test did not exceed the yield strength. On some cast parts, it is very difficult to
locate a section where the part was not over stressed. Allowing the yield or tensile strength
to be determined from separately cast bars that were poured from the same lot as the tested
part will insure that the yield or tensile strength thus determined will not be based on a part
previously over stressed.

(c) For cast pressure parts, cast test bars may be used in lieu of the specimens referenced
above. If used, cast test bars shall be produced, machined and tested in accordance with the
requirements of Section II. Cast test bars shall be poured from the same ladle of material,
under the same sand conditions, that the cast pressure part subjected to bursting is poured
from and shall receive the same thermal treatment as the cast pressure part subjected to
bursting.

SECTION IV, PART HG (Continued)

HG-502.3 (Continued)

(d) The design pressure P, psi, for pressure parts, tested under this paragraph shall be
computed by the following formula:

P = PB/5 X S/(Sa or Sm)
where
B PB = bursting test pressure
S = specified minimum tensile strength
Sa = average actual tensile strength of test specimens or cast test bars,
Sm = maximum tensile strength of range of specification.

HG-710.5

HG-710.5 includes mandatory requirements to place identification tags on boiler supply
and return valves. The issue with this mandatory language is that some individuals believe
it is essential to include the exact wording on the tags, only because the Code says “shall”.
Although there is good reason to have such identification and the advice it provides, the
piping, valves, and tags are outside the scope of Section IV and therefore not mandatory.

Delete HG-710.5 since it is outside the scope of Section IV.

SECTION IV, PART HF

HF-203 & HLW-203

Revised HF-203.2, HF-203.3 and HLW-203 to define ASME standard and Manufacturer’s
standard pressure parts and add footnotes 3, 4 and 5 to HF-203 and footnotes 1,2 and 3 to
HLW-203.

SECTION IV, PART HF (Continued)

HF-204.3(e) & Table HF-300.1 Note 12

The reference found under HF-204.3(e) to note (16) should be replaced by a reference to
Note (12) and the note itself should be revised to reflect that the conversion of 210 F is 99
C and not 98 C.

Revised to say “(e) For austenitic stainless steel materials only, the water temperature shall
not exceed 210°F (99°C). [See Table HF-300.1, Note (12).]

Table HF-300.1
Under notes:
(12) The water temperature shall not exceed 210°F (99°C).

Table HF-300.1

It is desired to use SF-568M, property class 10.9 material in Section IV construction
because that is the material from which metric fasteners are fabricated. Section II, Part A,
SF-568M, par X1.1.5 indicates that SF-568M, Class 10.9 mechanical properties are
purchased as SF-568M material and then recertified to SA-354, grade BD in accordance
with Section IV, paragraph HF-206. Adding this material to table HF-300.1 will eliminate
the time and expense of recertifing the SA-354 material. Since this material has been heat
treated, the maximum allowable stress should be the lesser of 20% of tensile or 25% of
yield.

HF-301.1

A request was received from a manufacturer for the use of:

EN 10025-2 – 2004 Edition – Grade S235JR (1.0038)
EN 10088-2 – 2005 Edition – Grade X6CrNiMoTi17-12-2 (1.4571)
EN 10217-1 – 2002 Edition – Grade P235TR2 (1.0255)
with Section IV, limited to hot water applications

Addition of three new materials:
SA/EN 10025-2 – 2004 Edition – Grade S235JR

SA/EN 10088-2 – 2005 Edition – Grade X6CrNiMoTi17-12-2

SA/EN 10217-1 – 2002 Edition – Grade P235TR2

HF-301.1

Section IV is requesting Section II provide two separate tables, HF-300.1 and HF-300.1M,
which will replace existing Table HF-300.1. The new Tables HF-300.1 and HF-300.1M are
to contain temperature dependant stress values from room temperature to 500F (275C) for
all materials currently listed in Table HF-300.1. Section IV and MPC have prepared both
tables and are requesting Section II approval. The allowable stress value for SA-193 B7
bolting material at room temperature has been corrected.

Table HF-300.1 has been replaced with two new tables HF-300.1 and HF-300.1M for US
Customary and SI units respectively. The new table lists temperature dependent allowable
stress values ranging form room temperature to 500 F (275 C). Correct the allowable stress
value of SA-193 B7 bolting material at room temperature to YS/4 (75/4 = 18.8 ksi.).

SECTION IV, PART HA

HA-302(d)

A manufacturer requested new paragraph (d) be added to the end of HA-302 in order to
allow the use of Sand Cast Aluminum Alloy EN AC-AlSif10Mg(a), F Temper having core
removal ports closed by welded patches. The use of welded patches, having the same
thickness of the adjacent material is proven as good engineering practice for this material
and in the foundry industry. Core of correct size and shape is necessary to obtain a sound
casting and therefore the suitable opening is required to remove the core.
EN AC-AlSi10Mg(a), F temper alloy is recognized by the BS EN 1706/1998 as A-class
(Excellent) ability to be welded.

Revise HA-302 by adding new requirements under new paragraph (d) as follows:

(d) Core holes in aluminum alloy castings may be plugged by welded patches made
of the same material as the castings under the following conditions:
(1) The welded plugs may only be used to plug holes required for the
manufacturing process, such as core sand removal. They shall not be
used for repair.
(2) Proof testing to establish design pressure is required and shall comply
with HA-402.
(3) The shop assembler shall hydrostatically test each casting per HA-406

HA-406.1

In the manufacture of several boiler products using a series of cast aluminum boilers of a
monoblock design that require no additional assembly (there are no boiler sections or
manifolds involved in these designs). These castings will have been tested at 2-1/2 times
MAWP by the foundry. Therefore, it is felt that it is not necessary to test them again at a
lower pressure.

HA-406.1 (Continued)

(a) Revised to say “ Hot water heating boilers marked for maximum allowable working pressures
not over 30 psi (200 kPa) shall have each individual section or boiler part subjected to a
hydrostatic test of not less than 60 psi (400 kPa) at the shop where made.
(c) The assembled boiler shall be subjected to a hydrostatic test pressure not less than 1 1/2 times
the maximum allowable working pressure.
(1) Cast aluminum monoblock boilers, boilers with a single section design that do not require
additional machining or assembly, do not require a second hydrostatic test at 1 1/2 times
the maximum allowable working pressure.
(a) Any additional machining, short blasting or grinding after the hydrostatic
test will require testing at 1 1/2 times the maximum allowable working pressure.

SECTION IV, PART HC

HC-211

Under the current requirements of HC-211 test bars are required per melting period and the
melting periods are limited to 8 hours. A foundry running a 10 hour shift is defined as
having 2 melting periods and is required to pour 4 test bars per shift. This change maintains
the minimum requirements, while removing penalties for foundries running shifts longer
than 8 hours.

NUMBER OF TESTS

For purposes of this requirement, a melting period shall not exceed 24 hr.

For tensile or traverse tests for each class of iron, one of more test bars shall be cast during each 4
hour period during the melt. No less than two test bars are to be cast from each melt, one during the
first half of the melting period, and the other during the last half of the melting period. For chemical
composition test samples, see HC-202.

During each eight hour period, one chemical composition test and either one tensile or one
transverse test shall be made on each melt (or each mixture if two or more mixtures of a different
class of iron are made in a given melt) for each controlling section (see HC-206) in the castings
made from each melt (or mixture).2

SECTION VIII, Div. 1 GENERAL

This summary of changes to Section VIII, Div. 1 of the ASME Code is not all inclusive and
contains the changes we consider most important to our clients. Please remember to use the Code
for actual requirements.

The 2011 Addenda to the Code become mandatory January 1, 2012. This addenda was printed on
white paper and was printed in its entirety. Also please note that Footnotes have been changed to
Endnotes and these endnotes are part of the Standard.

ASME will no longer issue addenda. The next edition of the Code will be issued in 2013 and then
issued every 2 years thereafter. Code Case Supplements will be published two times a year.
Interpretations will be posted on the ASME website at http://cstools.asme.org/Interpretations.cfm
in January and July of each year.

What ASME calls a “Special Notice” may be posted on the website prior to the 2013 Edition to
provide approved revisions to Code requirements. These revisions may be used upon issuance but
become mandatory 6 months after issuance. “Errata” to the Code will also be posted on the ASME
website to provide corrections. Errata are typographical or grammatical errors.

SECTION VIII, Div. 1 GENERAL (Continued)

ASME is phasing out the multiple stamps and moving to a single mark. The major driver
behind this change is that in order to fully protect the marks, ASME would need to register
marks in the more than 100 countries in which stamped equipment used. The use of a
single mark will allow ASME to register one mark in these countries thus making it easier
to afford greater protection of a single mark rather than lesser protection for multiple
marks.

during which a Manufacturer or Constructor would be able to use either one of the
applicable 25 current marks or the single mark. Use of the single mark would then become
mandatory on January 1, 2013. There will be a policy statement in the front of the Code
books describing this transition period and an implementing Code Case in both the BPV
and Nuclear Code Case Books.

Each stamp holder must go to ASME’s CA connect (http://www.caconnect.asme.org),
establish an account if they have not already and request the new Mark. ASME will
not be sending individual notifications of this to the stamp holders – It is up to the
stamp holders to independently request this new mark

Revise all Section VIII Div. 1 paragraphs to refer to the ASME Certification Mark instead
of the Code Stamp.

FORWARD

The ASME has determined that the Forewords are not part of the Code. Accordingly, a
proposal to move those portions of the present Forewords of the BPV Codes which are
perceived to contain mandatory and enforceable language into an appropriate location in
their respective Book Sections has been made.

One of those portions is in the 5th paragraph of the Foreword that addresses tolerances. This
action takes the exact words that currently reside in the Foreword on tolerances and place
them in the new paragraph. While coverage regarding tolerances is addressed (for example,
UG-80 and UG-81), it was felt that a dedicated paragraph was needed in view of the
broader range of applicability in which that these paragraphs may apply.

SECTION VIII, DIV. 1 INTRODUCTION

New Paragraph

U-5 Tolerances

Added New Paragraph, “The Code does not fully address tolerances. When dimensions,
sizes, or other parameters are not specified with tolerances, the values of these parameters
are considered nominal and allowable tolerances or local variances may be considered
acceptable when based on engineering judgment and standard practices as determined by
the designer.”

Table U-3

Many of the references in the current code books show obsolete references. The table has
been revised to update the year of acceptable edition dates. Referenced documents in U-3
have been updated. Dimensional standards are now shown as “Latest Edition” Documents
with P/T ratings and specific technical requirements show year of accepted edition.
Several new references have been added. The latest edition of ASME standards may be

SECTION VIII, DIV. 1 PART UG

UG-11

The revision is a restructuring of UG-11 to include rules for non-standard pressure parts;
rules for pressure parts, welded or non-welded, built to an ASME product standard such as
B16.5; and rules for pressure parts, welded or non-welded, built to a standard other than
ASME such as a Manufacturer’s standard. The documentation that a Manufacturer must
have in order to “satisfy himself that the part complies with the rules of the [Code] and the
design is suitable for the design specification.” has been increased

It also provides rules for allowing a Manufacturer to subcontract welding to another entity
for welding pressure parts that is to their own standard, and will also incorporate ASME
B16.1 as an acceptable product standard for fabrication of vessels to Part UCI.

This paragraph has undergone significant changes. A lot of the information that was in
UG-11(a) is now in UG-11(c). The manufacturer of the completed vessel is still
responsible to assure the parts supplied comply with this Division. The documentation that
Manufacturer must obtain in order to satisfy himself that the part complies with the rules of
this division and the design is suitable for the design specification has been increased. UG-
11(e) is a new paragraph allowing the use of a subcontractor to perform welding even
though the subcontractor is not a Code stamp holder. The paragraph details all the
requirements that must be met by the vessel and parts manufacturer.

UG-19

This item revises the marking and data report rules for combination units. It removes the
requirement that “parts of chambers” be marked or identified on the Data Report, since it is
sufficient that this requirement only apply to chambers, Added the requirement that
common elements of chambers not included in the scope of this Division be marked and
described on the Data Report, and reorganized the MDR and marking requirements for
combination units to reside in their own paragraphs. The paragraphs related to the marking
and MDR requirements for combination units were reorganized as well. UG-116(l) is now
UG-116(k).

This revises the marking and data report rules to:

1) remove the requirement that “parts of chambers” be marked or identified on the Data
Report, since it is sufficient that this requirement only apply to chambers,
2) add the requirement that common elements of chambers not included in the scope of this
Division be marked and described on the Data Report, and
3) reorganize the MDR and marking requirements for combination units to reside in their
own paragraphs.

Clarified the marking and data report requirements for combination units and common
elements adjacent to at least one Code chamber.
Reorganized the paragraphs relating to the marking and MDR requirements for
combination units. Renumbered UG-116(l) to UG-116(k)

UG-20(a)

• Cautionary note added to UG-20 “Design Temperature”
• References to WRCB 470 for suggested details for vessels in elevated temperature
service
• Non mandatory requirement

Experience has shown that some pressure vessels operating at temperature in the creep
range of the materials have experienced cracking after some period of operation. Such
cracking has most often occurred at locations that exhibit stress concentrations and/or local
thermal gradients, and weldments. Typical locations where cracking has occurred are as
follows:

Nozzle reinforcing pad attachment welds
Nozzle-to-shell junctions
Support attachment points
Other fillet welded attachments

Added a reference to WRC-Bulletin 470 “Recommended Design Details for Elevated
Temperature Service.” This is a cautionary note to help in preventing cracking in the creep
range.

UG-32(b)

This paragraph was deleted because it is not used anymore. The paragraphs will not be
renumbered due to the large number of references to these other paragraphs.

UG-39

• New Mandatory Appendix 41 for Electric Immersion Heater Support Plates
• Uses same methods as given in Part UHX for perforated plate
• Results in a more accurate, less conservative design than required by UG-39
reinforcement rules

The current rules for reinforcement of multiple openings in flat covers used to support
electric element heaters result in greater thicknesses than rules consistent with those in Part
UHX. Flanged electric immersion heaters consist of tubular electric heating elements
typically mounted in multiple penetrations in ASME B16-5 blind flanges. Under the
current Code rules and interpretations, a flanged electric heater element support plate is not
considered a tubesheet but rather an unstayed flat head or cover. Therefore, the rules in Part
UHX are not applicable and the cover thickness requirements are calculated using the
formulas and rules in UG-34 and UG-39. For multiple penetrations, the rules in UG-34
(c)(2) require the value under the square root sign in formula UG-34 (c)(2), Formula (2) to
be doubled for both operating and bolting calculations. This causes the thickness to be
unnecessarily greater than that computed using the Part UHX methodology. The Appendix
would establish mandatory rules for the design of electric immersion heater element
support plates that are specific to these products using the rules established in Part UHX,
specifically UHX-12 for “U” tube heat exchangers.

Typically blind flanges are used for the electric immersion heater element support plate.
However it is not uncommon for a manufacturer to be forced to use the next higher class of
blind flange in order to achieve the minimum thickness requirements for both operating and
bolting as calculated by UG-34 and UG-39. Moreover the required thicknesses as
determined by these rules are typically 20% to 30% thicket than similar calculations for
heat exchanger tubesheets subjected to the same pressure and temperature. The proposed
Appendix would establish mandatory rules for the design of electric immersion heater
element support plates that are specific to these products using the rules established in Part
UHX, specifically UHX-12 for “U” tube heat exchangers.

Revised to add a reference to Appendix 41 for electric immersion heaters and their design.

contained in documentation received by the vessel manufacturer for plate material. These
documents shall be either an MTR or a C of C and shall be prepared by the originator of the
data. The Inspector shall determine that this documentation represents the material and
meets the requirements of the material specification.

(a) Revised to read “Except as otherwise provided in UG-4(b), UG-10, UG-11, or UG-15,
requirements……

(1) For plates,2 the vessel Manufacturer shall ensure all requirements of the material
specification, and all special requirements of this Division, that are to be
fulfilled by the materials manufacturer have been complied with. The

Material Test Reports. The Inspector shall determine if these documents
represent the material and meets the requirements of the material specification.

UG-99(b)

Revised this paragraph to consider static head in hydrostatic test pressure calculations.
This means the gauge does not have to be at the top of the vessel as long as static head is
considered in the pressure calculations.

Paragraph (b) now says “Except as otherwise permitted in (a) above and 27-4, vessels …
… All loadings that may exist during this test shall be give consideration. The hydrostatic
test pressure reading shall be adjusted to account for any static head conditions between the
chamber being tested and the pressure gage.”

UG-99(f)

Vessels design and constructed for service under high vacuum (HV) or ultra high vacuum
(UHV) conditions are routinely not ASME Code stamped and certified. Vacuum vessels
are specifically excluded from the scope of Section VIII, Division 1 per the provisions of
U-1(c)(2)(h). As a result, HV and UHV vessels are often constructed in compliance with
AWS D17.1, or other similar standards which impose loose technical requirements, making
it difficult to invoke a standard of consistent design and construction quality for these
vessels. As a result, there are broad inconsistencies in the way manufacturers design and
construct vacuum service vessels, often compromising their performance. It would be
helpful for users to be able to specify construction and certification under Section VIII,
Division 1 rules to impose more detailed requirements for greater consistency in
engineering and construction quality. However, HV and UHV vessels have unique design
and service needs which often make full compliance with Section VIII, Division 1
impossible, precluding their certification and stamping under the provisions of U-1(c)(2).
To eliminate the existing barriers to “U” Code Symbol Stamping of HV and UHV vessels,
a set of alternative rules is being proposed as revisions to existing Code requirements for
pressure testing of vessels intended only for vacuum service.

This paragraph was revised to allow vacuum testing as an alternative for vacuum service
vessels, and to impose leak testing requirements for performing vacuum testing.

UG-102(a)

The definition of, “connected to the vessel,” is subject to interpretation. The text of the
paragraph is revised to clarify the intent of the connection. Also, this provides guidance for
static head considerations if the gage is not at the top of the chamber.

(a) An indicating gage shall be connected directly to the vessel or with a pressure line that
does not include intermediate valves. If the indicating gage is not readily visible to the
operator controlling the pressure applied, an additional indicating gage shall be provided
where it will be visible to the operator throughout the duration of the test. For large vessels,
it is recommended that a recording gage be used in addition to indicating gages.

UG-116(j)

Revised to clarify the marking and data report requirements for combination units and
common elements adjacent to at least on Code chamber. Also reorganized the paragraphs
relating to the marking and MDR requirements for combination units. Renumbered

UB-30(d)

UW-26(d) was revised (BC03-212) )to permit subcontracted welders to be used only at the
address on the Certificate of Authorization or the final installations sire. This is a
significant departure from past practice that permit the use of subcontracted welding at
locations other than the Certificate Holders address or final installation site. When this

Material Manufacturer: the organization responsible for the production of products meeting
the requirements of the material specification, and accepting the responsibility for any
statements or data in any required certificate of compliance or Material Test Report
representing the material.

Material Test Report: a document in which are recorded the results of tests, examinations,
repairs, or treatments required by the material specification to be reported. Including those
of any supplementary requirements or other requirements stated in the order for the
material. This document may be combined with a certificate of compliance as a single
document. When preparing a Material Test Report, a material manufacturer may transcribe
data produced by other organizations provided he accepts responsibility for the accuracy
and authenticity of the data.

APPENDIX 6

Added Paragraph (d) which says “Documentation showing that the required examinations
have been performed and that the results are acceptable shall be made available to the
Inspector.“

SECTION VIII, DIV. 1 MANDATORY APPENDICES (continued)

APPENDIX 8

Added Paragraph (d) which says “Documentation showing that the required examinations
have been performed and that the results are acceptable shall be made available to the
Inspector.”

APPENDIX 10

Added line (5) to paragraph 10-13(b) to state “Pressure parts documentation and
certifications ”The rest of the items were renumbered. Also, Line Item (b)(7) was revised
to say “Welders Qualification Records for each welder who welded on the vessel”

The intent of 10-13(b)(6) is to be able to identify which welder made each weld on a
pressure vessel; see UW-37(f). The text of the code should be clarified to show this.

UW-37(f), Welder and Welding Operator Identification, is clear that the intent of the code
is that identifying stamps are to be applied to vessel welds – or a record is to be kept as to
which welder welded each joint.

Paragraph 10-13(b)(6) revised to be clear that records should be kept in accordance with
UW-37(f).

APPENDIX 23

Removed the maximum limit of 1500F for copper and copper alloy tubes.

APPENDIX 24

24-1(a) was revised to add considerations of loads other than pressure. In 24-1(f), retainer
requirements were modified. And in 24-1(d) added an alternative to equation 5.

26-16. Figure 26-13 was revised to clarify the requirement for circumferential welds
attaching the bellows element to the shell or weld ends.

APPENDIX 35

Revised 35-4(a) to clarify that the Manufacturer is responsible for submitting the
inspection and quality control procedure and the Quality Control System to the AIA of
record, the legal jurisdiction and the ASME designee for review and acceptance.

SECTION VIII DIVISION 2

Annex 2.C

Section VIII, Div. 2 Code was rewritten in 2007 Edition the words that permit
Manufacturers with multiple locations, each with its own Certificate of Authorization, to
transfer pressure vessel parts from one location to another without Partial Data Reports
were inadvertently deleted. The deletion of these words creates a hardship for those
manufacturers that fabricate parts in one location and transport them to another location for
assembly into the final vessel.

As a historical note the revision to Section VIII, Div. 2 in the 2002 Addenda (BC97-401)
AM-105, AS-310 permitted the transfer of welded parts between one Manufacturer’s
Multiple Plant Locations

Add Paragraph 2.C.2.3

“Manufacturers with multiple locations, each with its own Certificate of Authorization,
may transfer pressure vessel parts from one of its locations to another without Partial Data
Reports, provided the Quality Control System describes the method of identification,
transfer, and receipt of the parts.”

Paragraph 5.5.1

Added new.7 for weld seam peaking when a fatigue analysis is required

Paragraph 6.1.6.3.a) and c)

Revised to add consideration of peaking when the weld joint is operating at a temperature
where the allowable stress is in the time dependent regime

The current words of 6.1.6.3.a are essentially the same as AF-136 from the A06 version of
Div 2. However, since VIII-2 now goes into the creep regime, creep should be addressed in
addition to fatigue. There have been documented failures of Category A welds failing in
creep due to the additional bending stress as a result of peaking. Paragraph 6.1.6.3 is

modified to include vessels that operate where time dependent properties govern the
allowable stress.

SECTION VIII DIVISION 2

For welded joints exceeding 2 inches in thickness, Table AF-142.1 of the 2004 Edition of
Section VIII Div 2 (incl. 2006 Addenda) listed the maximum allowable offset in welds as a
function of the thickness, with a maximum of 3/8 inch in longitudinal joints, or 3/4 inch in
the case of circumferential joints. When the 2007 Edition of Div 2 was published, the limit
was shown as a maximum of the two criteria. This has the effect of increasing the
maximum allowable offsets (see comparison on page 3 of the proposal file). To be
consistent with the “old” Div 2, the “Max” expression in Table 6.4 should be replaced with
“Min”. For information, a table showing the values from Table AF-142.1 of the old Div 2,
the current Table 6.4, and the revised Table 6.4 after the proposed changes are made.

The provisions on KM-211.2(c) have been used to circumvent the requirements of KM-
211.1(a) and (b) for very thick forgings. KM-211.2(c) currently permits Charpy V-notch
test specimens for very thick forgings (e.g. a flat head >20 inches thick) to be taken
immediately adjacent to the surface. While the impact properties at the surface may be
acceptable, the properties at the 1/4 t location may be very poor. This action eliminates the
exemption for very thick forgings and clarifies that for contour shaped forgings, the intent
is to determine the equivalent of the 1/4 t location as accurately as practicable and to take
the test specimens at that location.

Para KM-211.c

(c) For very thick or complex forgings that are contour shaped or machined to essentially
the finished product configuration prior to heat treatment, a drawing prepared by the
Manufacturer shall show the surfaces of the finished product which will be subjected to
high tensile stresses in service. The distance between this surface and the nearest quenched
surface is defined to be the thickness t.
Test specimens shall be removed from stock provided on the product. The coupons shall be
removed so that the specimens shall have their longitudinal axes at a distance t below the
nearest heat-treated surface. The midlength of the specimen shall be a minimum of twice
this distance, 2t, from any second heat-treated surface. In any case, the longitudinal axes of
the specimens shall not be nearer than 3/4 in. (19 mm) to any heat-treated surface. This is
known as the t by 2t test location.
For forgings that are contour shaped or machined to essentially the finished product
configuration prior to heat treatment, find the interior location that has the greatest distance
to the nearest quenched surface. Designate this distance t/2. Test specimens shall be taken
no closer to any quenched surface than 1/2 of this distance (1/4 t location). The mid length
of the specimen shall be a minimum of t/2 from any second quenched surface.

listed in table QW/QB-422 with a minimum tensile strength values may be used for
procedure qualification except as modified by the following paragraph.” The “following
paragraph” says, “If an unlisted base metal has the same UNS number designation as a base
metal listed in table QW/QB-422, that base metal is also assigned that P-number or P-
number plus Group Number. If the unlisted base metal is used to procedure qualification,
the minimum tensile values of the listed base metal shall apply for the tension test
specimens.” Also added “Material produced under an ASTM specification shall have the
same P-Number or P-Number plus Group-Number and minimum specified tensile value as
that of the corresponding ASME specification listed in table QW?QB-422. (e.g., SA-240
Type 340 is assigned P-No 8, Group 1; therefore, A240 Type 304 is P-No 8, Group 1.)”
