The difference between rigid coupling and flexible coupling

The piping system with rigid coupling joints is in a rigid state. The pipe cannot produce axial and radial displacement, making the system inflexible. After the pipe clamp is clamped, it can form a rigid integration with the steel pipe. When the span of the spreader is large, When connected, the pipelines rely on their own rigid support for connection, and are suitable for risers and general pipeline systems.

Flexible coupling joints allow the pipes to have partial axial displacement and rotation after connecting the pipes, making the system flexible. After the relatively misaligned steel pipes are connected, there is a gap between the ends of the two steel pipes to adapt to the expansion and contraction of the pipes. The pipe clamp should maintain normal working pressure under the maximum allowable stall and misalignment condition. Flexible clamp joints have the ability to withstand a certain end load. There is no obvious difference between the effects of rigid and flexible joints in indoor projects, buildings, and shopping mall pipeline installations. Flexible clamp joints play a more obvious role in underground engineering and are better than rigid connections. It is mainly suitable for pipeline systems with thermal expansion and contraction, line extension, deflection angle, and vibration, such as pump rooms, etc.
