Pipe Support News

October 24, 1997

News from Quality Control
PT&P’s QC Manager, has lead several testing efforts including three at cryogenic temperatures. Two of these tested coils in springs, the other tested an anchor for cryogenic pipelines. Tests on aluminum travel stops proved successful and these are a new PT&P standard. Other new standard procedures cover bonding processes.

The picture at left shows PT&P’s QC Manager as he is preparing to test the pressure capability of a 4″-150 lb. rated metal expansion joint unit. The unit is sealed and gauged as air is introduced through a fitting on the top blind flange. As a pump supplies air, the gauges indicate how much pressure the unit is experiencing.

Replacing a Spring Coil With Stainless Steel Bellows

October 21, 1997

Spring coils are so pervasive in design of pipe supports that our collective paradigm limits our ability to consider alternatives. The photograph below shows an example of a pipe support designed for the special environment of an off-shore platform which uses a stainless steel metal bellows instead of a spring coil.

This customer was concerned about the corrosive environment and the salt water which will occasionally flow over the pipe support. The rolled plate on the left will be welded to a structural pipe on the platform. A riser clamp (not shown) will be attached on the right. The stainless steel bellows was designed with the proper spring rate and movement.

WHK Historical Research Completes PT&P's History

October 17, 1997

Dr. William Kellar of WHK was the Project Historian for a team which prepared archives and a book covering the first twenty years, 1978-1997, history of PT&P. Dr. Joseph Pratt of the University of Houston served as Project Editor. Kellar conducted extensive interviews with current and former customers and employees and lead the effort of sorting through the many documents, photographs and stories about experiences many of us shared. PT&P will publish the book in 1998. A big “thank you” to Bill and all who contributed to this project. Happy reading to all!

PT&P Collaborates on PDS Software

October 4, 1997

Piping Technology & Products is collaborating with other sponsors to create a pipe support module for an industry leading plant design software package, PDS. The concept for the pipe support module was developed by another company, and PT&P became involved in August 1997.

Programming has been added which will enable users of PDS to easily integrate PT&P pipe supports and hardware components with their PDS models. To prepare for the project, PT&P has participated in 4 weeks of training at Intergraph’s site in Huntsville, AL learning the PDS system and the EDEN programming language.
