Description

Our clamp type rubber joint also known as absorber, expansion joint, shock absorber, compensator, flexible joint and hose clamps, it use clamp instead of flange and bolt, install the pipe orifice on both sides of rubber joint to the connecting pipeline, then use clamp to fix connection between rubber joint and pipelines; just loosen the clamp when dismounting. In this way to compensate pipeline displacement which is caused by thermal expansion and water delivery. Clamp type rubber joint composed of inner rubber layer, fabrics enhancement layer and outer rubber layer, then by molding vulcanization and combine with clamp. Inner rubber directly bear abrasion and corrosion of medium delivered; outer rubber layer protect rubber joint from being damaged and corroded by external environmental; enhancement layer is the pressure-bearing layer, giving rubber joint strength and stiffness, the working pressure of rubber joint depends on material and structure of enhancement layer. General rubber joint’s inner and outer rubber layer use NR, SBR or BR; oil resistant rubber joint use NBR; acid-base resistant, high temperature resistant rubber joint use EPDM. For clamp materials, there has stainless steel and carbon steel, commonly we use stainless steel.Comparing to flange type rubber joint, clamp type rubber joint has following features:Clamp type rubber joint saved cost of flange and bolt, saved project expenses;Clamp type rubber joint has no need of upsiding down edges, which simplified production process, saved raw material;Clamp type rubber joint simplified installation and maintenance, promoted working efficiency;Clamp is made from stainless steel, which is anti corrosive. Diameter is from DN32 to DN1000, pressure grade is from 0.25mpa to 1.0mpa.
