PipeCustomized Expansion Joints

Expansion joints absorb movement and vibration in systems that convey high temperature commodities such as steam or exhaust gases. A typical type of expansion joint for pipe systems is a bellows style which can be manufactured from metal (most commonly stainless steel), Teflon, or an elastomer such as Neoprene or EPDM.

A bellows is made up of a series of one or more convolutions, with the shape of the convolution designed to withstand the internal pressures of the pipe and flexible enough to accept the axial, lateral, and/or angular deflections.

Expansion joints are also designed for other criteria, such as noise absorption, anti-vibration, earthquake movement, and building settlement. Pipe expansion joints are also known as compensators, as they 'compensate' for thermal movement.
