Henan Liwei  Industry  Co., Ltd. is a professional manufacturer of piping system products. Our main products include Single/Double Sphere Rubber Joint, expansion joint, Ball Joint, Flange, steel dismantling joint, Carbon Steel/Stainless Steel Metal Expansion Joints, Fabric Expansion Joints, valve parts, pipe parts, various kinds of stainless steel compensators, duct fabric compensators, advanced soft sealing gate valves and flange duckbill valve.

Single sphere rubber expansion joint effectively dampen and insulate downstream piping against the transmission of noise and vibration generated by mechanical equipment. Noise and vibrations caused by equipment can cause stress in pipe, pipe guides, anchors and other equipment downstream. The Single Sphere Rubber Expansion Joints will help relieve noise and vibration occurrences in a pipe system. Water hammer and pumping impulses can also cause strain, stress or shock to a piping system. Install Single Sphere Rubber Expansion Joint to help compensate for these system pressure spikes.

Making materials of Yinlong single sphere rubber expansion joint:
• Body (Outer Layer & Inner Layer): EPDM NBR and Neoprene Rubber
• Reinforcing Layer: nylon fabric with rubber
• Wire: Stainless Steel Wire
• Material of flange: carbon steel, stainless steel and ductile cast iron
