The groove type bellow expansion joint also called a clamp type bellows expansion joint. The groove type bellow expansion joint is a compensating element. Using the effective telescopic deformation of the corrugated pipe of the working body to absorb the dimensional changes caused by thermal expansion and contraction of pipelines, pipes, containers, etc., for compensating for axial, lateral and angular displacement of pipelines, pipes, vessels, etc. For example: a new type of special grooved type bellow for fire protection.
Super high temperature resistance, corrosion resistance, high pressure resistance
