CADWorx and Analysis University Returns to Houston


Article and photo by Bill Beazley


The popular CADWorx and Analysis University (CAU) program has returned to Houston after a few years’ absence. CAU is produced by Intergraph CADWorx and Analysis Systems. The program had been co‐located with the Hexagon Live program in Las Vegas. Hexagon is the parent company of Intergraph.

CAU is known for quality presentations from practitioners who use ICAS tools, including

 

 - CADWorx

- CAESAR II

- PVElite

- GT Strudl

 

Presentations also include add‐ons and complementary software from other vendors.

Many customers had found it hard to gain approval for travel to Las Vegas. In addition, CAU lost its unique and distinctive technical character amongst the broad array of Hexagon products. Hexagon, in addition to Intergraph’s products, offers software and hardware for manufacturing, surveying, mapping and other applications. A large number of Intergraph and ICAS customers work in the Houston area.

CAU 2016 continues for two days followed by a special symposium. For more information, consult:

Houston SPED Chapter Gets Rare Look at Paulin Research


Article and photos by Bill Beazley

The Houston SPED Chapter got a rare look at the laboratories and research results of Paulin Research Group ("PRG").  Lead personally by PRG President, Tony Paulin, SPED members were shown the equipment and test specimens used to develop Stress Intensification Factors (SIFs), monitor crack growth in piping components and vessels, and verify piping deflections predicted by analysis.  PRG also provides FEA software products and consulting services to the pressure vessel and piping industries.  The chapter meeting was September 15.

Mr. Paulin began the meeting with an explanation of why SIFs as calculated by the current B31.3 piping code were inaccurate.  For code fatigue purposes, SIFs are the ratio of the nominal stresses in the component unders study to the nominal stress that will cause failure in a straight pipe at a given number of cycles. Early fatigue based SIFs were first developed in the early 1950s by A.R.C. Markl using tests at Tube Turns.  Everett C. Rodabaugh of Battelle Memorial Institute was on the original Markl team and later improved the equations now used in the code.  Markl’s tests and Rodabaugh’s corrections and enhancements where scaled up from data collected mainly on 4” schedule 40 pipe.

Paulin’s tests now show that the equations that scale up these SIF results to other pipe sizes and wall thicknesses are in some cases overconservative and in some cases unconservative.  Revisions will be coming out soon as ASME B31 J, an ASME standard to produce stress intensification factors (i-factors), flexibility factors (k-factors), and sustained load factors for metallic piping components used in B31 piping analysis.

Paulin’s team including Fred Hendrix, Willy Lock, Dr. Delin Wang, and Jose Del Valle is also studying the growth of cracks in piping components are they progress toward fatigue failure.

The results might be used to predict the risk of failure as a focus of further inspection.

Finally, the attendees were treated to software product expected to be announced at CAU September 19-20.  Mr. Paulin was thanked by SPED Houston Chapter President, Doug Coberly.

Pipe Shields for Beginners: Insulated Pipe Supports... for Commercial Applications Webinar


Date: Thursday, July 28, 2016

Register for either time slot: 10:00 am OR 2:00 pm CDT

Note: Time Zone is CDT * Central Daylight Savings Time / GMT -6h

 

This webinar will give you an introduction to Pipe Shields, Inc. and its unique line of pre-insulated pipe supports, slides, guides and anchors that it developed and patented over it's 40 year history. It will cover various designs, commercial applications (chilled and heated water lines, HVAC systems and low pressure steam lines), installation and maintenance procedures and the benefits of using pre-insulated pipe supports (vs. doing insulation in the field). This webinar will be delivered by Albert Dizon, General Manager of Pipe Shields, who has been working with pre-insulated pipe supports for 30+ years. Join us and receive some of his experience and wisdom!
