Products Description
A bellows type EPDM expansion joint is a kind of bellows expansion joint made of EPDM material. When the piping system is subjected to external factors such as temperature changes, pressure fluctuations or installation errors, the bellows-type EPDM expansion joints are able to absorb and compensate for these displacements, thus maintaining the stability and sealing of the piping system. The bellows section is made by a special molding process and has multiple corrugated structures which give it good flexibility and displacement compensation. Bellows type EPDM expansion joint is a robust and flexible component that provides effective stress relief and system protection in various industrial applications.
