Double Flange Limit Expansion Joint
Double flange limit expansion joint is made of carbon steel or ductile iron with an integrated structure, combining expansion, compensation, limit and anti-pull-off functions. It can freely adjust axial expansion distance, accurately compensate thermal expansion and contraction, installation errors and foundation settlement displacement. It is extremely convenient for installation and adjustment, greatly improving construction efficiency. Equipped with high-quality rubber seals, it features reliable sealing, stable pressure resistance and no leakage, as well as good shock absorption and noise reduction performance. The limit device effectively prevents pipeline pull-off and ensures safer operation. With high structural strength, corrosion resistance, aging resistance and easy maintenance, it is widely used in water supply, municipal, fire fighting, HVAC and various industrial pipelines, making it an ideal fitting for long-distance pipelines and pump valve connections.
