1.Rubber expansion joint introduction: 

1)Rubber expansion joint 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)Rubber expansion joint can be used for lift and transportation of raw water and sewage,transportationof water supply cooling cycle water thermal power ,condensate water of metallurgy industry and chemical industry.

2.  Threaded type double sphere with counter flange rubber expansion joint

This kind of rubber expansion joints four types:
