Spring Hangers and Spring Supports are used where vertical movements of the piping are not allowed to be restricted by rigid hangers. The Variable Spring Hanger consists of a pre-compressed spring coil in a cylindrical casing, with a load-and travel indicator. The load changes proportionally to the movement, depending on the spring rate. Variable Spring Hangers are designed to enable an adjustment of the distance between Variable Spring Hanger and pipe or equipment connection.
