Parameter of rubber expansion joint:
Single shpere rubber bellow
Double Sphere rubber bellow
Threaded rubber bellow
Products feature 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 compensationforthermal expansion and contraction caused by temperature change.
6.Standard sizes range from 1.25" through 80".
Factory supply 2inch double sphere galvanized bspt union type rubber expansion joint
Rubber expansion joints provide a wide range of rubber support with a reinforcement that depends on the pressure required. These types of expansion joints isolate noise and vibration. When it comes to damage caused by vibration and movement, each rubber expansion joint protects piping systems by avoiding such hazards
The rubber expansion jointhas 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.
