Product Features
The flexible expansion joint with force-transmitting mechanism consists of a flanged flexible expansion joint, short pipe flanges, force-transmitting screws, and other components. The short pipe has a certain amount of expansion and contraction displacement, which can be adjusted according to the on-site installation dimensions during installation and maintenance. Under normal operating conditions, it can effectively transmit axial thrust throughout the entire pipeline. This not only improves operational efficiency but also provides a degree of protection for equipment such as pumps and valves.
