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 or seismic motions.

H.M Supply Co. designs and manufactures bellows expansion joints from the simplest standard expansion joints to highly complex expansion joints which are designed especially on the basis of individual customer requirements. Metal expansion joints are single or multi-layered stainless steel expansion joints with a high level of expansion absorption and a low spring rate.
