Twin Sphere Rubber Expansion Joint

Product Description

Huayuan rubber joint is also called expansion joints or rubber expansion joint. It is a

pipe joint of high-flexibility, high

gas tightness, resistance to medium and climate. rubber expansion joints are

flexible connectors made from natural or synthetic elastomers in which special

fabrics are embedded to provide physical reinforcement. rubber expansion joints provide a proven and flexible solution to accommodate many types of

movements and requirements of industrial plant and equipment.

Twin Sphere Rubber Expansion Joint

Features of Rubber Expansion Joint

1.Small volume, light weight, good elasticity, easy installation and maintenance.

2.Installation can generate horizontal, axial and angular displacement, from pipe barrier heart, flange is not parallel to the limit.

3.Work to reduce structural transmission of noise, vibration absorption ability.

4. Good sealing performance and scalability, easy to use. Internal high density, can endure high pressure, elastic deformation effect is good.

5.Use of rubber of high elasticity, high resistance, solvent resistance, weather resistance and radiation resistance and other advantages can reduce vibration and noise, and play the role of compensation for thermal expansion and contraction caused by temperature change.

The application of rubber expansion joint

Because the rubber joint has good comprehensive properties,

so it is widely used in chemical industry, construction, water supply, drainage, circulating water,

oil, light and heavy industry, frozen, sanitary, plumbing, electricity and other infrastructure projects. fire protection, papermaking, pharmaceutical, petrochemical, shipbuilding, water pump, compressor, fan and other piping systems.
