Why Attend?

Here are just a few of the issues we'll help you deal with in this seminar:

Large D/T pipe may not perform like beams!


Large D/T (>100) piping systems can be considerably more flexible than beam models predict.

WRC 335 suggests that errors of one order of magnitude or more are possible. Deforming elbows interact with other pipe and intersections to further complicate the stress state. Flexibilities modeled at intersections can drop loads and stresses by as much as ten times!

Most large structures are not rigid.

Large structures can deflect during erection, wind or earthquake loads considerably more than rigid models predict. Support interactions with flexible panels, plates and heads can redistribute stress and loads.

Pipe & Equipment Interact

The flexibility of heads, cones, large nozzles, supports and piping can considerably affect the displacement, supports, loads and stress distributions in large systems.

New Technology in Flange Analysis

Flanges are usually overdesigned, and new proposed rules for flange requirements have been rejected. European codes are permitting thinner flanges because they protect better against leakage. Learn how you can accurately design flanges and predict & protect against leakage.


How do you Handle Multiple Nozzles?

Simplified approximate methods are often used to evaluate single nozzles in a head, but are not appropriate for multiple nozzles and close-proximity nozzles.


Problems with Zick Analysis require FEA

Zick Analysis does have drawbacks.  For example, vessel stresses at the horn of a saddle can often be far higher in reality than predicted by Zick analysis.  This is why some engineers choose full encirclement saddles.  FE/Pipe accurately predicts the true state of stress and compares to code allowables.



Each day combines engineering theory with detailed, practical example problems that apply the theory learned. A wide variety of component types are examined using the latest FEA software from Paulin Research Group. You will learn how to acheive code compliance and cost-effective, accurate analysis and designs.

Course notes provided contains valuable reference material that you will use long after the course.


Option 1 (Days 1 and 2)

Option 1 training is targeted for the beginning to intermediate user that is not thoroughly familiar with ASME code interpretation or PRG software. Sample course topics are listed below.

Option 2 (Days 3 and 4)

Option 2 training includes advanced topics for customers that have experience with application of finite element software to piping and pressure vessel problems. The content is hands-on as industrial problems are modeled from begining to end.

Please note that option 2 topic content is flexible and we can accomodate coverage of requested equipment modeling. We urge customers to provide drawings of equipment they would like to model beforehand.
