Allied Packing and Rubber, Inc. offers a wide variety of pipe expansion joints. Pipe expansion joints are necessary in systems that convey high temperature substances such as steam or exhaust gases, or to absorb movement and vibration.
A typical joint is a bellows of metal (most commonly stainless steel), plastic (such as PTFE), fabric (such as fiberglass) or an elastomer such as rubber. A bellows is made up of a series of convolutions, with the shape of the convolution designed to withstand the internal pressures of the pipe, but flexible enough to accept axial, lateral, and 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 the thermal movement.
