Variable Spring Hangers

スプリングハンガ (SPRING HANGER)

SH-VSA-C / SH-VSB-F

Variable Spring Hangers & Supports are used for supporting piping and equipment where vertical movement is required. They are generally used at points where stress due to load variation does not have a harmful effect on the overall piping system. Allowable load variability is generally within 25% of the design load as described in MSS-SP-58. Evaluations are required where the piping has high flexibility, to ensure stress changes due to the load variation does not overstress the piping system.
