Description

Single sphere rubber bellow for 6 inch is one pipe joint with high elasticity, high air tightness, medium resistance. It’s also called single ball expansion joint, single bellow flexible rubber joint,etc.
Single sphere rubber bellow for 6 inch has been widely used in chemical industry, oil industry, construction, water supply drainage, fire production industry, etc.
● Reduce the vibration and noise of pipeline system. Improve the service life of plumbing system.
● Compensate the pipeline’s displacement. Absorb movement, improve thermal stability.

Advantages

1. Flange has been painted
Flange paint treatment to ensure that in the case of wet rust is not easy.
2. Improved tightness.
3. Reduce the damage caused by friction.
The radian of flange inner forged surface is 67 degrees, which reduces the damage caused by friction between flange and rubber ball by more than 95%.
4. Good quality of flange
The rubber joint USES good quality flange, the service life increases 5 years above.
5. EPDM
The rubber ball is made of EPDM rubber, containing more than 40% rubber, which has a longer service life than conventional rubber.
