Flexible Joint Pipe Manufacturer Of Rubber Bellow Expansion Joint
Product Description
Rubber Bellow Expansion Joint is a flexible connector with a bellows-shaped rubber body, designed to absorb vibration and noise, compensate for axial, lateral, and angular movements, and reduce stress in piping systems. Made from high-quality rubber materials such as EPDM, NBR, or NR and reinforced with fabric or steel rings, it provides excellent elasticity, sealing performance, and corrosion resistance. Rubber bellow expansion joints are widely used in water supply, HVAC, wastewater, industrial pipelines, and marine systems to protect pipelines and connected equipment and extend service life.
