This is in continuation to my previous post (walk through-piping).
Generally, when we talk about Pipe stress analysis basics, we tend to quickly jump to Failure theories, B31.3, Caesar II, Static & Dynamic, offshore /onshore, jacketed piping etc.
Walk through Pipe stress is to ease into piping stress world with its polite introduction to curious techies, without having hold on Forces/moments/displacement equations.
Pipe Stress Analysis Basics will be taken next.

Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid
Industrial process piping (and accompanying in-line components) can be manufactured from wood, fiberglass, glass, steel, aluminum, plastic, copper, and concrete. The in-line components, known as fittings, valves, and other devices, typically sense and control the pressure, flow rate and temperature of the transmitted fluid, and usually are included in the field of Piping Design (or Piping Engineering). Piping systems are documented in piping and instrumentation diagrams (P&IDs). If necessary, pipes can be cleaned by the tube cleaning process.
"Piping" sometimes refers to Piping Design, the detailed specification of the physical piping layout within a process plant or commercial building. In earlier days, this was sometimes called Drafting, Technical drawing, Engineering Drawing, and Design but is today commonly performed by Designers who have learned to use automated Computer Aided Drawing / Computer Aided Design (CAD) software

R.M. Baker, & D. L. Passmore. (2012, August 16). Cracking the ethane cracker. Invited presentation at the 2012 WIB Symposium, “Innovation through Integration: Re-Inventing the Workforce System,” sponsored by the Pennsylvania Association of Workforce Investment Boards, State College, Pennsylvania. (see http://pawib2012.tumblr.com)
Shell Chemical LP, a petrochemical unit of Royal Dutch Shell, signed a land purchase option agreement with Horsehead Corporation, a producer of specialty zinc and zinc-based products and a recycler of electric arc furnace dust, to evaluate a site in western Pennsylvania for a potential petrochemical complex. The site is located in Potter and Center Townships in Beaver County near Monaca, Pennsylvania, which is 40 miles northwest of Pittsburgh.
The site currently houses a Horsehead’s plant for zinc products and contains the only electrothermic zinc refining facility in the Western Hemisphere. If the land purchase option is exercised, Horsehead Corporation will vacate the Monaca facility by April 2014.
Shell’s plans for the complex include an ethane cracker that would process ethane feedstock from “wet” Marcellus Shale gas to supply ethylene for a wide variety of intermediate sales to industries and for final end use in manufactured products. “Cracking” involves heating and separating the large hydrocarbon chains found in fossil fuels such as natural gas and petroleum into lighter hydrocarbons such as ethane.
In this workshop, a report by the American Chemical Council (ACC) [Shale Gas and New Petrochemicals Investment: Benefits for the Economy, Jobs, and US Manufacturing] of the potential static U.S. job and tax impacts of ethane production is examined. Then, the results are presented from an analysis prepared by researchers from Penn State’s Institute for Research in Training & Development (IRTD) of the potential dynamic economic and demographic impacts of the Royal Dutch Shell petrochemical complex planned for western Pennsylvania. Special attention is paid to the implications that these impacts estimated by ACC and the IRTD hold for regional workforce development in Pennsylvania.

Are you unfamiliar with rigid-flex PCB design? Before you attempt to design a rigid-flex board, read Amit Bahl's column, originally published in the June 2013 edition of The PCB Design Magazine. Learn the basics.
Ceramic bearings are typically constructed with a ferrous inner and outer ring or race with ceramic balls in the place of steel. Ceramic bearings offer many advantages over all steel bearings, such as higher speed and acceleration capability, increased stiffness, lower friction and more. Ceramic balls are also nonconductive. Ceramic bearings are available in all standard industry configurations such as, angular bearings, thrust bearing, pillow block bearing, needle bearings, and roller bearings.

Increasing the Strength and Reliability of Press FitsDesign World
Retaining compounds increase the strength and reliability of traditional press and shrink fits. Retaining compounds improve the distribution of stress, which increases maximum load transmission and performance. They create a physical barrier that eliminates fretting, oxidation and galvanic corrosion, which increase service life.
Recent chemical advances in retaining address assembly process variables including gaps, surface finish and cleanliness ensuring consistent performance. Application equipment provides repeatable precision dispensing.
• Recent innovations in retaining: tolerance, higher temperature resistance, primerless formulas
• New data on retaining advancements: test results on strength, oil and chemical tolerance
• How to use retaining compounds to augment a press fit for increased reliability
• Application case histories for retaining including cost and performance

Putting the SPARK into Virtual Training.pptxCynthia Clay
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.

If concrete requires expansion
joints to survive 100 deg C

periods of many months, how
can one expect refractory to
survive 1,700 deg C swings in

– Ferrules are specifically designed
to fit each application’s tubesheet
and unique set of operating
conditions.
– Have been successfully used in
waste heat boilers with tube
diameters from 20mm to 200mm.
– Particularly compatible with
systems that use oxygen
enrichment and those with very
large tubesheets.
– Available in a range of alumina
compositions to suit, up to 99.6%

• No castable is required between the
ferrules. During installation, some
castable would be needed around
the perimeter of the ferrules, but
the amount needed would be quite
small in comparison to a
conventional installation. This
system can typically be installed in
about one third of the time it would
take to do a conventional
installation. Additionally, refractory
cure times can often be reduced
during startup.

12. blaschceramics.com
• Replacement costs are quite low. If
the plant owner wishes to inspect
the tubesheet, they would typically
need to remove the ferrules. For a
conventional installation this is a
time consuming and costly activity
because the castable must be
removed and the ferrules cannot be
reused. For Blasch precast ferrules,
such activities are much simpler;
typically only 10% of the ferrules
need to be replaced, which
substantially reduces maintenance
costs and downtime.

consumption.

– Ferrules are supplied complete
with all necessary refractory fiber
wraps and gaskets.
– Installation involves simply
sliding each ferrule into the tube
sheet.
– Installation is typically completed
from the bottom of the
tubesheet to the top.
– The assembly is finished with a
castable or plastic refractory
periphery.
– No metal anchors are required.
Ferrules are held in place
through friction with the boiler
tube ID’s coupled with the
peripheral refractory.

• Basic Refractory Design
• Ferrule Design Philosophy
• Ferrule Design Features
• Refractory is not a metal
– It does not act the same way under
high temperature conditions.
– It is not characterized to the degree
that metals are.
– All 95% Aluminas are not created
equally.
• Design guidelines
– Never design with interior sharp
angles. Anything that looks like an
interior corner will amplify stress and
act as an origination site for cracking.
– Whenever possible, design to avoid
placing refractory in tension.
Thermal gradients can place
refractory in tension.
– Never interfere with the need for
refractory to expand and contract
– Design so as to work with thermal
cycling, not against it.
Basic Refractory Design

• Blasch hex ferrules should
never be mortared
together, or kept from
acting independently in any
way.
• This is particularly critical in
very large tubesheets,
where enormous stresses
can develop.

impacted only by a
maximum of six
