Galvanized flanged double arch flexible rubber expansion joint for pipelines
This rubber expansion joint consists of rubber pipe, made of inner glue, multi-layer proofinf and cord fabric and outer glue abd metal woggle joint.
It is applicable for the connection of inlet and outlet pipes of various fancoil sets of air conditionings in the guest rooms of hotels and restaurants.
Production process:
This product use the high air tightness of rubber elastic medium resistance of weathering and radiation resistance, high strength and a little cold and heat stability of polyester cord skew and the composite by high pressure, high temperature mold vulcanization and become.
Application :
Air, compressed air, water, sea water, hot water, oil, acid, alkali, etc.
Installed next to mechanical equipment or between the anchor points of a piping system to:
(1) Absorb Pipe Movement/Stress
(2) Reduce System Noise
(3) Isolate Mechanical Vibration
(4) Compensate Alignment/Offset
(5) Eliminate Electrolysis,
(6) Protect Against Start-Up Surge Forces.

Rubber joints make use of the advantages of high elasticity, high gas, medium resistance, weather resistance and radiation resistance of rubber, which can reduce vibration and noise of pipes, and compensate for thermal expansion and cold shrinkage caused by temperature changes.
