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.
Rubber expansion joints Hand Spool Type1021 are hand-built rubber expansion joints, different from the molded expansion joints, the surface of 1063 are with fabric-strip-like texture. The extrordinary advance compared with molded expansion joints is it can make special small quantity items with different size and length cost-effectively.
