Corrugated compensator belongs to a compensation element. Effective expansion using its working body of the corrugated pipe deformation, dimensional changes to absorb the pipeline, conduit, vessel expansion and contraction caused by other reasons, or compensation pipes, conduits, containers and axial, transverse and angular displacement. Can also be used for vibration and noise reduction. Widely used in modern industry. Corrugated compensator, habit is also called expansion joint, or expansion joint. The main working body formed by the corrugated pipe and end pipe, bracket, flange, catheter and other accessories composition. Rubber joint is also called rubber pipe flexible joint flexible rubber joints, soft rubber joints, rubber joint, high pressure rubber joints, rubber shock absorber, compensator. Connection points by loose flange type, fixed flange and screw type 3; according to the structure can be divided into single ball, double ball, reducing body, bending and pressure of 5 sphere coil. From the outside and the inside layer of glue, ply and steel wire ring tubular rubber parts, the vulcanization molding and then the metal flange or parallel joints loose assembly. This product can reduce vibration and noise, and can play the role of compensation for thermal expansion and contraction caused by temperature change, widely used in all kinds of pipeline system. Rubber joint is also called flexible rubber joints, soft rubber joints, rubber flexible joint, flexible joint, shock absorber, shock absorber, damping throat pipe, is a high elasticity, high air tightness, pipe joint media resistance and weather resistance. The product uses the rubber elasticity, high air tightness, solvent resistance, weather resistance and radiation resistance is, using polyester cord fabric oblique high strength, strong stability and the hot and cold composite, high pressure, high temperature mold vulcanization after a.
