Single Arch/Sphere rubber expansion joint, which also named vibration absorber, compensator, connecting hose and so on, is a pipeline connection with high elasticity, high-pressure sealing, mediator endurance, and weather resistance.

Their features of Rubber Expansion Joint are:
1. Small in size, light weight, good elasticity, convenient installation and maintenance.
2.There’ll be horizontal, axial, angular displacement when installing, without restrictions of pipe blocking and flange unbalance.
3. Structure transmission noise can be reduced when it is working and it has a strong cushioning ability and so on.
4.Flexible rubber hose has high-pressure rubber joints in high temperature, acid, oil pipelines are more effective in preventing the erosion of corrosive medium on the rubber joint ,so they can improve service life.
5.Flexible rubber expansion joints, which is widely used in supporting pipelines of various industries, and have a good overall performance.

The reasonable combination of limited escapement and flexible rubber joint in the pipeline connection or pipeline with the requirements of displacement. Rubber joints can play the role of limiting the displacement. The connection between the flexible rubber joint and pump or valve,can play the the part of transmission equipping with the limited escapement. In this case, rubber joints will be the fine substitute of steel transmission joint.
