Overview |
|---|
Rubber expansion joints are also called flexible joint, rubber compensator or vibration absorber. Due to the flexibility of rubber, beside metal expansion joints, rubber expansion joints are always introduced to the piping system to solve some certain problems.
Rubber expansion joints Eccentric Rubber Reducer 1050 are molded with one wide arch. Beside absorbing vibration and offseting pipe movements, it is special made for pipingpipe reducing.

Pressure rating is for rubberbellows on base of 31 ℃, when higher temperature the pressure rating will reduce.
Movements in above table arenon-concurrent.
Test pressure is 1.5 times the pressure rating. UNICK rubber expansion joints could take 3 times design pressure for safety..
