Cast Iron Dismantling Joint is mainly made of the original double flange power transmission joint with the addition of connecting short pipe flanges. It is a pipe fitting specially developed for the installation and disassembly of valves. It is adjusted during the lifting process of heavy valves, especially ball valves. The length of the double flange power transmission joint expands the gap between the valve and the pipeline. After the valve is hoisted, adjusting the limit bolts to extend the power transmission joint can better install the valve, and the power transmission joint can be effectively installed during the pipeline operation. The radial displacement of the pipeline is absorbed but the axial displacement of the pipeline cannot be absorbed.

Wholesale Cast Iron Dismantling Joint factory
Our company Cast Iron Dismantling Joint can be equipped with large valves such as ball valves, butterfly valves, check valves, smashing valves, etc. It is also suitable for circulating water pipelines, condensate water pipelines, petroleum and petrochemical pipelines, sewage treatment pipelines and water supply and drainage pipelines in power engineering. The force transmission joint is also suitable for the corners of large-diameter circulating water pipelines, which can effectively compensate the displacement and vibration of the corner pipelines, especially for long-distance pipelines. Since the tightness between the rigid connection flanges is easily affected by the varicose of the pipeline itself, Therefore, the use of force transmission joints can protect the pipeline well, and the pipeline has a good compensation and release space when it is deformed by cold and heat.
Cast Iron Dismantling Joint is composed of metal casting or welding, and the loose part is made of trapezoidal rubber sealing ring. Under the action of gland and bolt, the principle of rubber compression elastic deformation is used. Forcing the sealing ring to deform between the outer walls of the expansion tube of the joint body to perform static sealing. Metals and sealing rings are selected strictly according to performance and user requirements. The exterior of the material is coated with high-strength anti-corrosion paint, and the connecting bolts of each part are made of high-strength carbon steel or stainless steel. Because there is a certain gap between the body and the telescopic tube, it has a certain axial and radial displacement.
This series of Cast Iron Dismantling Joint can effectively compensate and relieve the thrust of the pipeline and the blind plate in the pipeline, and also facilitate the installation, maintenance and replacement of pumps and valves. It is an ideal accessory product in the pipeline installation and operation industry.
