PT&P Pre-Insulated Pipe Supports Catalog

September 19th, 1998 No comments

The PT&P catalog for cold shoes, hot shoes and other pre-insulated pipe supports is near completion. Draft copies of the catalog were distributed to certain customers for review. PT&P is now using the feedback received as a basis for revising and improving our first draft. Finished copies of the PT&P Pre-Insulated Pipe Supports Catalog will be available in late 1998.

PT&P Sponsors University of Houston Student Project

September 15th, 1998 No comments

PT&P again sponsored a University of Houston Mechanical Engineering student design project during the Fall ’97 term. The team of Sandra Ramos, Dorsa Froutan, Irma Adame and E.J. Del Valle titled their project Deasign, Test and Modeling of Cryogenic Pipe Supports. All were Seniors enrolled in MECE 4334: Mechanical Engineering Systems Design. Similar courses are required for Industrial Engineering, Electrical and Computer Engineering students.

The U of H faculty requests companies to submit problem statements for projects they are willing to sponsor. If their project is chosen by a student team, companies designate an engineer-in-charge who helps their faculty consultant advise the students. The students prepare a written proposal defining their plan during the first four weeks and make weekly progress reports thereafter. Companies provide facilities and equipment as required. The students prepare a final written report and make an oral presentation at their campus at the end of the semester.

This team did a series of experiments both at ambient and cryogenic temperatures using pipe shoes with polyurethane (PUF) of various densities. They studied compressive strength, heat transfer rates and clamping forces required to maintain contact with a pipe under axial loading. This was the fifth project sponsored by PT&P. We thank these students for their hard work, and we wish them much success during their professional careers.

Customers Mail Back Survey Cards

Thanks to the many customers who mailed back survey cards from our Fall ’97 mailings. We received a number of good suggestions and potential topics for future technical bulletins. The statistics on four Yes or No questions are:

  • 91%: Yes, the PT&P technical bulletins are useful to their jobs.
  • 89%: Yes, their job requires use of the PT&P catalogs.
  • 99%: Yes, PT&P newsletters cover topics of interest to them.
  • 61%: No, the photos on PT&P’s annual calendars should not be changed.

Figure Conversion Chart on the Web

September 15th, 1998 No comments

PT&P’s World Wide Web site will soon host another valuable technical resource for engineers around the world. A figure number conversion tool will allow engineers to enter alternative figure numbers (Grinnell and others) and find matching PT&P figure numbers.Engineers are encouraged to replace alternative figure numbers with corresponding PT&P figure numbers in their technical specifications.  Look for the PT&P Figure Conversion Tool online at our web site.

SWECO Builds Tanks to Supply Fuel by Helicopter

September 4th, 1998 No comments

Sweco Fab, Inc., PT&P’s ASME code pressure vessel shop, is building its third order for stainless steel tanks used to transport diesel fuel to off-shore platforms by helicopter.  Special calculations were required to verify the air-worthiness of the skid-mounted tanks.

Pipe Support News

October 24th, 1997 No comments

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 21st, 1997 No comments

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.

Stainless Steel Bellows Used as 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 17th, 1997 No comments

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 4th, 1997 No comments

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.

PT&P Establishes a Plus Agreement

The plaque states “In an effort to demonstrate the unified pursuit of quality and cost reduction through a long term relationship, this agreement is established with Piping Technology and Products. The mutual goal… is to achieve a high standard of excellence in both product and service to our clients through innovative work processes and shared cooperative effort.” Piping Technology was the first vendor selected for this recognition.

PT&P Acquires U.S. Bellows, Inc.

September 1st, 1997 No comments

In July of 1997, Piping Technology & Products, Inc. acquired U.S. Bellows, Inc. from Ketema Process Equipment in California. As a part of the purchase, PT&P acquired all U.S. Bellows manufacturing equipment, all design and technical software, and the company’s historical files. During the month of July, PT&P personnel worked hard to move the manufacturing equipment from California to Houston. As a part of the transition, former U.S. Bellows engineers conducted a one-week training session at PT&P’s facility in Houston.

U.S. Bellows, Inc. has been servicing the industry since the 1960s and has a long history as a reliable expansion joint manufacturer. U.S. Bellows, Inc. will now operate as a division of Piping Technology & Products from our facility in Houston. U.S. Bellows will continue to offer the same expertise in expansion joint design, production, and customer service that has always been the PT&P trademark.

PT&P acquired R.M. Engineered Products metal expansion joint business in 1995 and relocated that equipment to our 15 acre manufacturing facility in Houston, Texas. The R.M. Engineered Products equipment and the newly acquired U.S. Bellows operating machinery combine to make U.S. Bellows and Piping Technology & Products among the most capable expansion joint/metallic bellows manufacturers in the world.
