Pipe Expansion Joints are necessary in systems that absorb movements and vibrations, or convey high temperature commodities such as exhaust gases or steams. Bellows is a typical expansion joint for pipe systems that can be manufactured from metals like stainless steel, fabric such as glass fiber, elastomer such as rubber or plastic such as PTFE. A bellow is made with a series of one or more convulsions whose shape is designed to withstand the internal pressures of the pipe but at the same time it is made flexible enough to bear the axial, angular and lateral deflections. Other criteria like noise absorption, earthquake movement, anti-vibration and building settlements are also considered during the designing of expansion joints. Metal expansion joints need to be designed as per the guidelines of EJMA while the Fabric Expansion Joints need to be manufactured as per the guidelines laid out by the Quality Association for Fabric Expansion Joints.
