Introduce of transmission expansion joint
C2f type double flange loose sleeve transmission joint is a new product connecting pumps, valves, pipes and other equipment with pipes. They are connected by full bolts to form a whole, with a certain amount of displacement, which is convenient for installation. It can withstand the axial pressure of the pipeline. In this way, it can be adjusted according to the on-site installation size during installation and maintenance, which not only improves the working efficiency, but also plays a certain role in protecting the pipeline equipment such as pumps and valves.
