Issue Date: 30 July, 2003
Next Planned Update: 1 July, 2008 Positive Material Identification Requirements
1 Scope
1.1 This SAIP provides functional guidance for Plant Inspectors performing Positive
Material Identification (PMI) in all Saudi Aramco Facilities.
1.2 This SAIP also instructs the assigned Saudi Aramco Inspector, on color coding
of PMI verified materials, reporting and documentation.
1.3 This SAIP does not include PMI requirements for the following:
As per SAES-A-206 Paragraph 1.3.
2 Purpose
The purpose of this SAIP is to ensure that the nominal composition of the materials
specified has been correctly supplied and installed in the fabricated equipment or
piping. Also, it ensures that the correct welding by testing the welds has been
performed.
Commentary Note:
PMI is a testing method which is independent of any material certification, mill test reports
and marking or color coding of materials.

4 Definitions
All definitions of SAES-A-206 apply with the following addition or changes:
Saudi Aramco Inspector: The person authorized by the Saudi Aramco responsible
inspection unit to verify implementation of the requirements of this SAIP and SAES-A-
206.
Construction Organization: The organization responsible for fabrication, installation
or repair of the alloy material in the field (e.g., maintenance organizations).
PMI Instrument Operator: Trained technician assigned by Plant Inspection Unit
supervisor to operate the PMI testing machine and record the PMI testing result.
5 Responsibilities
The Assigned Inspector shall verify that the proper color coding and PMI tests are
conducted and that the installed materials are of the specified metallurgy. In case a
discrepancy is found, the inspector shall initiate an Equipment Deficiency Report
(EDR) and ensure that the requirements of this SAIP and SAES-A-206 are satisfied.
6 Instrument for PMI Analysis
6.1 Instruments for performing the PMI analysis of weld and the base metals is as
stated by SAES-A-206.
6.2 Both method and frequency of calibration and standardization shall be based upon
equipment manufacturer's recommendations. Records shall be maintained for the
checks and the date of calibration noted in the PMI report (Attachment-I).
6.3 When the inspector doubts the reliability of the measurement, he may calibrate
the instrument on shorter periods (e.g., on weekly basis or before every use).
Page 3 of 10

6.4 In addition to the manufacturer's standard calibration samples, certified samples
with the traceability of "known" material shall be made available for a random
(spot) check.
6.5 The date of the latest calibration of the instrument shall be stated in the PMI
report. (Attachment-I)
7 Personal Qualifications
The person(s) performing the PMI test should be knowledgeable about all aspects of
operation of PMI test equipment and the PMI test method used. Qualification of the
person performing the PMI test, including training and experience, should be
documented and submitted for review and approval by the responsible inspection unit.
Personnel shall be trained, tested, and certified to:
a) Safely use the PMI analyzers(s) (i.e., electrical arcing, X-Ray emission or
chemical testing methods).
b) Properly apply material specification such as ASTM and ASME.
c) Fully understand the PMI requirements, including the verification method to be
used, the period during fabrication when verification will be conducted, and the
method of marking and color coding verified material and segregation and
reporting non-compliant material.
8 Positive Material Identification General Requirements
8.1 When PMI testing is performed by the material supplier or third-party agency,
the Company should review and approve the adequacy of the material PMI
program and testing procedure of the fabricator or material supplier prior to
testing.
8.2 PMI shall be conducted before any post weld heat treatment, hydro test, painting
or insulation of any equipment or piping.
8.3 The area to be tested shall be solvent cleaned to remove any grease/oil/paint.
8.4 Surface (base metal and welds) to be examined shall be prepared by light
grinding to remove any rust/scale as per manufacturer's recommendations.
8.5 Weld surface of overlay or clad restoration shall be prepared by removing 2-3
mm of weld metal.
8.6 The PMI test report shall be reviewed prior to hydro test and made part of the
hydro test package supporting documents.

8.7 The responsible inspection unit shall audit the PMI test program to ensure its
effective functionality. The Operation Inspection Division of the Inspection
Department can be contacted for assistance.
9 Alloy Items Subject to PMI
The following components shall be subject to PMI testing in accordance with this
procedure.
- Plates (heads, shells, tube sheets, etc) and internals such as trays if required by the
purchase order
- Forgings
- Flanges
- Pipe and fittings such as tees, elbows, reducers, and special pipe components
- Valves (body and bonnet) internals as per SAES-A-206
- Thermowells
- Furnace tubes and fittings
- Casings for pumps, compressors, turbines
- Alloy welds joining pressure parts to pressure parts
- Heat exchanger tubes
- Metallic alloy gaskets
10 Extent of Verification
As per SAES-A-206.
11 Elements for Verification
As per SAES-A-206.
12 Acceptance Criteria
As per SAES-A-206.
13 Re-Verification / Rejection Criteria
As per SAES-A-206.
Page 5 of 10

14 Marking and Color Coding
As per SAES-A-206 and Attachment III.
15 Reporting and Documentation
15.1 The PMI report form (Attachment-I) shall be completely filled out by the
assigned inspector/technician for each PMI analysis.
15.2 A log shall be maintained (see form in Attachment-II) to identify each
component that has been alloy verified and the results.
15.3 The Report should be part of the permanent Equipment Inspection Record.
