PT&P manufactured 266 variable spring supports for a refinery in Texas. The variable spring hangers include chained travel stops for ease of disengagement and reinsertion during plant shutdowns. Variable springs (a type of Compression spring) are used in a wide range of applications (including various Low Carbon Capital projects, CO2 removal units, and Infrastructure improvements) to support the piping system. The variables are fabricated from carbon steel and hot-dipped galvanized to protect against corrosion. The PTP-2 variables were designed for loads up to 13,850 lb. and movements up to 0.1875” upwards. The PTP-4 variables were designed for a maximum load of 15,050 lb. and movements up to 0.8125” upwards. Each spring hanger underwent standard load testing and QC tests. PT&P also provided constant supports for loads that remain uniform throughout the deflection cycle and sway struts for controlling vibration and shock loading while restraining movement due to thermal expansion for this order.

Live Webinars are worth 1 PDH Credit for TX Professional Engineers
The Compact Spring Support Webinar will cover key objectives, background, and leading industry problems related to process equipment nozzles (both rotating and non-rotating equipment). First, we will review the challenges involved in the design and analysis of piping with respect to process equipment nozzles. Secondly, we will discuss the types of chronic problems and failures related to process equipment nozzles and present (or introduce) the Compact Spring Support as a solution. During our discussion, we will explain why chronic problems with process equipment exist, describing current design practices as they relate to industry code standards and how the Compact Spring Support addresses these problems directly and effectively. And finally, we will take a quick look at the technical data and sizing program.
