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 Slip On Type 104N are molded with corrugated convolutions. Different with other types, Type 104N expansion joints are completed with stainless steel clamps, it connects pipes with clamps instead of flanges or threaded unions.

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 thepressure rating. UNICK rubber expansion joints could take 3 times designpressure for safety..
