Single Ball Flange Rubber Bellows Expansion Joint Custom NBR EPDM Rubber Stainless Steel Flange
Flexible rubber expansion joints are composed of rubber spheres and metal flanges, with the flange ends connected to pipe flanges.
Materials for pump and valve-specific expansion joints: They feature corrosion resistance, wear resistance, acid and alkali resistance, and non-hygroscopic properties; they also have good elasticity and low hygroscopicity; they can resist thermal expansion and reduce pipe diameter.
They reduce thermal expansion or stress caused by temperature changes during pipeline transportation. They are one of the most commonly used components in pipeline systems, featuring a compact size, lightweight design, easy installation, reduced installation space, and material savings. During operation, they generate some displacement, which helps reduce vibration and noise in pipelines with significant vibration (such as pump systems).
