1.    The pipe expansion joint is simply a bellows element with flanges as end connections with weldingless.  Due to formed-in-one bellow and inset-O ring structures, the contained fluid has better sealing effect and no leakage under reduced setup times and less cost.

2.    Weldingless anti-shock joints could avoid stress concentration and grain boundary corrosion resulting from welding thermal effect.

3.    The product locates the flow input/output ends to isolate high frequency and low amplitude vibrations from piping equipment and to eliminate noise.

4.    The materials and specification could be assigned according to customer requirement.
