Rigid and flexible conduit joints: selection and application in pipeline systems

Rigid conduit joints: the guardian of stability and safety
Rigid conduit joints play an irreplaceable role in straight and slightly curved pipeline systems with their sturdy structure and stable connection performance. Such joints are usually made of high-strength materials such as metal, and are tightly connected between pipelines through threads, flanges or welding. In environments that require high stability and sealing, such as the petrochemical industry, rigid conduit joints become the first choice.

In the petrochemical industry, pipeline systems often undertake the important task of transporting high-pressure, high-temperature, flammable and explosive media. Therefore, the stability and sealing of pipelines are extremely high. Rigid conduit joints, with their excellent rigidity and sealing performance, can ensure the stability and safety of pipeline systems under high-load operation. Especially in large-diameter pipelines and high-pressure pipelines, rigid joints can effectively prevent deformation or leakage of pipelines due to pressure fluctuations or temperature changes, providing strong guarantees for the safe operation of the entire system.

Flexible conduit joints: flexible response to complex environments
Compared with rigid conduit joints, flexible conduit joints perform well in dealing with pipeline systems with large bends and many corners, as well as in environments that need to withstand the impact of natural disasters such as earthquakes. This type of joint is usually made of elastic materials, such as rubber, metal bellows, etc., and has good flexibility and seismic resistance.

In pipeline systems with large bends and many corners, flexible conduit joints can easily adapt to the bending deformation of the pipeline, reducing the stress concentration and wear caused by the bending of the pipeline system. At the same time, its good flexibility can also effectively absorb and disperse the energy of the pipeline under dynamic loads such as vibration and impact, and improve the overall stability and durability of the pipeline system.

When natural disasters such as earthquakes occur, flexible rigid conduit joints play an irreplaceable role. Its good seismic resistance can reduce the degree of damage to the pipeline system caused by earthquakes and reduce the risk of pipeline leakage and rupture. Therefore, in earthquake-prone areas or pipeline systems that need to withstand the impact of natural disasters, flexible conduit joints have become an indispensable and important component.
