Types that support piping from below would be types (F and U). Types that support piping from above would be types (A, B, C, D, E, and G), as in the above examples. ![]() The next step would be to select a support type. The key to selecting a constant support style would be the space available for that support above, below and around the piping (see below). SIZING CONSTANT SPRING SUPPORTSīoth constant support styles, style 100 (with a vertical coil housing orientation), style 200 (with a horizontal coil housing orientation), function in the same manner. 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. To perform a Pipe Stress Analysis, PT&P will need Isometrics and overall specifications for the line. – Perform a Pipe Stress Analysis to determine exact load and movement. – Weigh the Piping to determine the load and estimate movement from existing spring support – Estimate the load based on the pipe and media specification and estimate movement from existing spring support For these situations, PT&P has the following solutions: Another issue that comes up from many customers is the need to replace spring supports for which the load information has been lost. Beyond the Pipe Stress analysis, we will need elevation, attachment type, and any space constraints. ![]() We can quote directly from the stress analysis. 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. Spring Supports sizing is determined by a Pipe Stress Model which assesses the thermal growth and associated stress on the piping, nozzles, etc. 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. If the variation exceeds 25%, a constant support hanger should be used. The maximum recommended variation according to MSS standard from the operating load is 25% for variable spring hangers. 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. maximum recommended variation according to MSS standard from the operating load is 25% for variable spring hangers.
