Spring supports sizing is determined by a pipe stress model which assesses the thermal growth and associated stress on the piping, nozzles, etc. The pipe stress model determines how the piping can be designed to move and avoid placing under stress on the nozzles to equipment and the piping itself.
Having started as a pipe stress engineering company, PT&P has deep experience in pipe stress analysis. We can quote directly from the stress analysis. Beyond the pipe stress analysis, we will need elevation, attachment type, and any space constraints. Another issue that comes up from many customers is the need to replace spring supports for which the load information has been lost. For these situations, PT&P has the following solutions:
- Estimate the load based on the pipe and media specification and estimate movement from existing spring support.
- Weigh the piping to determine the load and estimate movement from existing spring support.
- Perform a pipe stress analysis to determine exact load and movement. To perform a pipe stress analysis, PT&P will need isometrics and overall specifications for the line. PT&P is almost always very cost-effective for pipe stress analysis. If drawings are unattainable or you don’t have access to the ISO drawings, we can perform laser scanning on the piping system and generate the drawings.
