DN50-DN800 Water Pipe Fittings Rubber Elastomer Expansion Joint

China Professional Supplier Double Sphere Rubber Expansion Joint PN10 / PN16 NBR EPDM Flange End

1. PRODUCT PROFILE

Expansion rubber joint is known as shock absorber, pipe shock absorber, shock proof box and soft joint. From the appearance ofdouble sphere rubber expansion joint and single ball rubber joint, its installation length is longer than that of single ball rubber joint, which solves the shortage of short installation length of rubber joint. Double sphere rubber expansion joint can be used when long rubber joint needs to be installed, but double sphere rubber expansion joint is strictly prohibited to be installed beyond the limit. The double sphere rubber expansion joint is mainly composed of the working theme rubber ball and the flange at both ends. The rubber is relatively soft, which can reduce the dynamic and noise, and can compensate the thermal expansion and cold contraction caused by the temperature change. Therefore, the double sphere rubber expansion joint is destined to play an important role in the pipeline system.

2. FEATURES

· Reduce pipeline system vibration and noise

· All rubber compounds for lining are specifically formulated to provide maximum sound and heat insulation as well as abrasion resistance
· A strong, bias-ply construction, high-strength nylon fabric inside rubber Round steel rings embedded in the liner give maximum strength to the expansion joint while under pressure or vacuum service
· Flanges are full-faced and make an integral part of the joint to insure a tight reliable seal, no gasket are necessary

· Solve the problem of axial movement, transverse movement, angular movement

· Acid resistance, alkali resistance, corrosive resistance, oil resistance, heat resistance

· If use on overhead, can match with elastic support to tighten up

· If pipeline pressure is high, use bolt connect the flange both ends
