DIN PN16 6inch EPDM Galvanized Carbon Steel Flanged Rubber Bellows
Expansion Joints
Product Introduction
Rubber joint is a kind of connector widely used in various pipeline
systems, it is mainly composed of rubber balls and metal flanges,
with high elasticity, high air tightness, medium resistance and
weather resistance.
Product Role
1.Noise reduction
2.Avoid vibration conduction
3.Compensate for displacement
4.Convenient pump and valve connection
5.Absorption of thermal expansion and contraction
6.Prevention of corrosive medium erosion
7.Reduced Pipeline Vibration and Noise
