Flexible rubber couplingintroduction:
1) This product can greatly reduce pipeline system shock and noise. And can fundamentally resolve pipe joints displacement, axial stretch and non-concentricity.
2) By using different materials, it can be made many kinds to cater for different medium and environment. Such asacid resistance, alkali resistance, corrosion resistance, oil resistance and heat resistance etc.

3) The material is purerubber, sealing is very good. It is in light weight, very easy for installation . This product has long life performance, but must be not contact with sharp metal instruments to avoid piercing the sphere.

4) The productcan be used for lift and transportation of raw water and sewage, transportationof water supply cooling cycle water thermal power ,condensate water ofmetallurgy industry and chemical industry.

Compared withsingle sphere rubber joint, double sphere rubber joint's advantages are itsdisplacement is larger,instantaneous pressure on the largerdeformation and so on, especially when installed in the export part of the pump.When the pump starts, instantaneouspressure is much higher than working pressure; double sphere rubber joint willreflect its advantages. Larger displacement and lower rubber aging speed ofdouble sphere rubber joint will make better effects. However, its draft is verycomplex, requires high technical, so the cost is very high, thus the applicationnumber is smaller than single sphere rubber joint.
