BELLOWS PIPE

A pipe bellow is sometimes known as a metal bellows expansion joint. A pipe bellows are a major part of the expansion joint system. A rubber expansion joint can absorb vibration, some misalignment, and handle axial and limited lateral movement. A metal expansion joint uses bellows in the pipe system. The metal bellows handle thermal growth and pressure thrust. When a piping system gets warm the thermal dynamics associated with the piping material will grow. The pipe bellows are required to compress and protect the system from damage. A pipe bellows can consist of several convulsions and are sometimes Layard. The layers are called plys. The plys are used to lesson loads on structures and to add redundancy to the pipe bellows system... The cycle life may also be increased with different materials other than carbon steel. Exotic alloys such as Inconel, hastolly, and chrome-moly could be used. Careful attention to pressure thrust must be taken into consideration when designing a system..
