BF single flange limit expansion joint

　　The BF single flange limit expansion joint is a key component in pipeline systems. It mainly consists of a short pipe with a flange on one end, an expansion pipe, sealing elements, and a limit device. During pipeline operation, in the face of displacement caused by factors such as thermal expansion and contraction, and mechanical vibrations, the expansion pipe can slide flexibly within the short pipe to achieve expansion compensation, effectively alleviating pipeline stress. The sealing elements are made of high-performance rubber material, ensuring reliable sealing and preventing medium leakage. The limit device precisely defines the expansion range by adjusting bolts, avoiding excessive expansion and damage to the pipeline. This joint, with its single flange design, is easy to install, requiring only alignment with the corresponding pipeline flange. It is widely used in water supply and drainage, chemical engineering, construction, and other fields, ensuring stable pipeline connections, enhancing system operational stability, and reducing maintenance costs.
