Overview |
---|
Rubber expansion joints are also called flexible joint, rubbercompensator or vibration absorber. Due to the flexibility of rubber, besidemetal expansion joints, rubber expansion joints are always introduced to thepiping system to solve some certain problems.
Flange rubber bend 1070 is rubber made bend, it is one type of rubber eion joint. Flange rubber bend 1070 is made by mold. The same as rubber expanison joint 1010, it has embedded steel wire and rubber hook design, the matel flange will be floating on rubber. The normal designed bend are with 90 degree angule, the angule can be upon request.

Pressure rating is for rubberbellows on base of 31 ℃, when higher temperature the pressure rating will reduce.
Movements in above table are for one side, when both sizes move, the capabilitiese will reduce.
Movements in above table arenon-concurrent.
Test pressure is 1.5 times thepressure rating. UNICK rubber expansion joints could take 3 times designpressure for safety.
