China Manufactur standard China Screwed Double Sphere Flexible Rubber Expansion Joint factory and manufacturers

Manufactur standard China Screwed Double Sphere Flexible Rubber Expansion Joint

Short Description:

The single-arch product can reduce the vibration and noise, which can also solve the axial/lateral/angular movements/eccentric problems. Reinforcement layer of the bellows by Nylon cords and at both ends by hardened steel wire rings. The floating steel flanges are drilled according to DIN, ANSI, BS, JIS and other standards. If the piping pressure is much higher, reinforced bolts should be assembled together with flanges.
