Double sphere Bellows Type Expansion  has high pressure resistance, good elasticity, large displacement, balance pipeline deviation, good vibration absorption, noise reduction effect, convenient installation, can also greatly reduce the vibration and noise of the pipeline system, and can fundamentally solve the problems of interface displacement, axial expansion and different centrality of various pipelines. The rubber raw material belongs to polar rubber, with good sealing performance, light weight, convenient installation and maintenance and long service life, but avoid contact with sharp metal instruments to avoid puncturing the ball.
