Asme Corrosion Resistant Design Dn32 Pressure Ring Plumbing Material double Flexible Rubber Expansion Joint
Double ball rubber joint can be divided into single ball, double ball, different diameter body, curved ball and wind pressure coil.
The product can reduce vibration and noise, and can compensate thermal expansion and contraction caused by temperature change. It is widely used in various pipeline systems.
Double sphere rubber bellows coupling is generally consist of the inner and the outer rubber layer and fabric reinforced layer (the enhancement layer has a multilayer spreading cord fabric), vulcanization molded in high temperature and high pressure , then assembly together with rubber tube and metal flange or parallel joint sleeve.
Characteristics of double sphere rubber expansion joint
1. Small size, light weight, good elasticity, easy installation and maintenance.
2. Horizontal, vertical and angular displacements can be generated during installation, which is not limited by eccentric and non-parallel flanges of user pipes.
3. Vibration and noise reduction function
4. Strong corrosion resistance and long service life.
