Expansion Joint is a product that maintains the piping system and protects equipment by absorbing high stress magnitude on pipes due to outer temperatures that may influence energy delivering pipes, pipe expansion or contraction caused by temperature changes in fluids, equipment vibration problems, wind pressure or earthquake.

Spring Hangers are used to carry the dead weight of the piping system at a given support while allowing movement resulting from thermal expansion or contraction of the piping system. It is used in places where heat displacement is low, has simple structure and low price.
