PRODUCT
The limit compensation joint is composed of components such as a loose sleeve compensation joint and a limit expansion pipe, to prevent leakage or damage of the compensation joint caused by excessive displacement of the pipeline. It is a device used to absorb axial displacement and bear pressure and thrust within the allowable displacement range for loose sleeve connection of the pipeline.
The double flange limit expansion joint is composed of main components such as the body, sealing ring, gland, and expansion short pipe. On the basis of the original performance of the loose sleeve expansion joint, a limit screw is added, and double nuts are used to lock at the maximum expansion amount. The pipeline can freely expand and expand within the allowed expansion and contraction amount, and once it exceeds its maximum expansion and contraction amount, it reaches a limit to ensure the safe operation of the pipeline.
It is particularly suitable for connections in pipelines with vibration, certain degrees of curvature, and bends. The force transmission compensation joint is composed of a flange loose sleeve compensation joint, a short pipe flange, a force transmission screw, and other components. It transmits the pressure and thrust of the connected parts and compensates for pipeline installation errors, without absorbing axial displacement. It is a device used for loose sleeve connection with accessories such as pumps and valves. During normal operation, axial thrust can be transmitted to the entire pipeline. This not only improves work efficiency, but also provides certain protection for equipment such as pumps and valves; The short pipe has a fixed expansion displacement, which can be adjusted according to the on-site installation size during installation and maintenance.
