What is an Expansion Joint?

An expansion joint is a device used to allow movement in a piping system while containing pressure and the medium running through it.

Frequently, thermal growth, equipment movement, vibration or pressure pulsation can cause movement in a piping system. When flexibility for this movement cannot be designed into the piping system itself, an expansion joint is the ideal solution.
