Metal Expansion Joint

An expansion joint is any apparatus containing one or more metal bellows used to absorb dimensional changes such as those caused by thermal expansion or contraction of a pipeline, duct, or vessel and to absorb vibrations caused by engines, pumps, motors, etc.

In other words, a metal expansion joint is a device primarily formed by flexible bellows used to absorb movements in a piping system while containing pressure and a medium running through it.

The key element of an expansion joint is the bellows. The bellows is a flexible element consisting of one or more corrugations and the end tangents.
