PT&Ps’ constant support hangers are principally used to support pipes and equipment subjected to vertical movement due to thermal expansion at locations where the transfer of stress to other supports or equipment can be critical. If the variation exceeds 25%, a constant support hanger should be used. maximum recommended variation according to MSS standard from the operating load is 25% for variable spring hangers.
Our constant support hangers are designed per MSS, ANSI, and ASME standards. The MSS standard provides for a tolerance of 6% in the constant load through the travel range. The cam is designed such that the distances from the main pivot changes to compensate for the variable resistance during compression of the coil. The constant resistance to a load is achieved by combining a spring coil with a cam which rotates about a main pivot point.

When you work with PT&P, you can be assured that no other company has seen and solved more issues around Piping Systems than we have. We have performed Field Service work in 41 countries, conducted over 1,000 plant audits, and worked with almost every major EPC, Petrochem, Chemical, and Power company. We have approximately 480 employees including 400+ production employees, 50+ design engineers, and 10 Industrial Engineers at our Houston Headquarters and other facilities. Today, PT&P is the only major global manufacturer of Engineered Pipe Supports and Expansion Joints. However, our roots in engineering are core to our DNA and how we approach all aspects of the business. Over the last 40+ years, we've expanded and are now best known for manufactured products. Dow was so pleased, they placed a large scale order to roll out the solution across all Dow plants, which allowed our founder to quit his job, and start PT&P. Our founder got his start by designing a thick-walled expansion joint for Dow Plaquemine. (PT&P) was founded as a pipe stress engineering firm in 1975. Piping Alignment and Pipe Strain Solutions.
