Expansion joints by GMI.

Expansion joints

The GMI expansion joint is an important contributor to the protection of your installations. The purpose of the expansion joint is to compensate for mechanical variations in the pipes, whether these are caused by expansion or vibration. According to their construction, our metal or elastomer expansion joints can be used for axial, lateral, or angular movements.
