Flexible and rigid joints
Thread Content
I would like to ask everyone, what is the difference between flexible joints and rigid joints? How to tell it from appearance?
Flexible joints generally refer to a rubber-like structure that can be stretched or twisted in the joint. Rigid joints are hard connections, such as those using two flanges.
Flexible joints generally refer to pipe joints that are relatively flexible. Pipe flexibility is a concept that reflects the ease of deformation of the pipe. It represents the ability of the pipe to absorb thermal expansion, contraction and other displacement deformations through its own deformation. When designing, one or more of the following measures are generally used to increase the flexibility of the pipeline:: Change the direction of the pipeline ； Choose waveform compensator, sleeve compensator or spherical compensator ； Use spring supports and hangers.
Rigid and flexible both belong to groove connections. The flange connection mentioned on the second floor should not have much to do with this. The specific distinction should be based on functional characteristics.: 1. Rigid joint (suitable for pipes without deflection); 2. Flexible joints (suitable for pipes with axial displacement and rotation)
Rigid joints are direct rigid connections, such as flange connections. The flexible joint connection method makes the system flexible and allows certain angular deviation and relative misalignment of the steel pipe. After the steel pipes are connected, a gap is left between the ends of the two steel pipes to accommodate the expansion and contraction of the pipes. Pipe joints should maintain normal working pressure under maximum allowable deflection and misalignment. Flexible joints have the ability to withstand a certain end load. End load refers to the ability of the pipe joint notch to withstand the axial load along the steel pipe.
ha! Thank you! Now I have a general understanding! :handshake
