Specifications

expansion joint
1.the competitive price
2.the big scal
3.good integral function

expansion joint

1.the joint coould primarity reduce the vibration and the nose of the piping system .completely solving the different piping problems as displacement of joint ,axial flex and etc.

2.According to different material  requirment,  product could be  made as acid ,alkali proof ,corrosion proof to suit different medium  and enviroment

3.The material are good sealing ,light weighting ,easy to fix and maintain,also has longworking expecting .
