Generally speaking, dismantling double flanges transmission joint series products belong to metal manufactures. It has high tensile and compressive strength, superior performance of soft seal, convenient loading and unloading. And it has been used in electric power, metallurgy, water supply and drainage, sewage treatment and other industries. It mainly acts on the connection between water pump, valve and pipeline. It has the function of multi-direction displacement in the pipeline operation, which can alleviate the blind plate thrust in the pipeline operation and play a certain protective role in the pipeline, especially provides great convenience for the installation and maintenance of the pipeline. However, the transmission joint should be used at the outlet of the pump and the corner of the pipe, because the transmission joint can transmit the blind plate thrust to the pump and all parts of the pipe through the bolt to avoid the impact damage caused by the thrust concentration in the pipeline or near end of the pump.

Dismantling double flanges transmission joint is mainly made by adding connecting short pipe flange on the basis of original double flange transmission joint. It is a pipe fitting specially developed for the installation and disassembly of valve. In the lifting process of heavy valve, especially ball valve, the length of double flanges transmission joint is adjusted, the gap between pipes is enlarged, and when the valve is hoisted, we can better install the valve after the limited bolt is adjusted, and the transfer joint is elongated. In the process of pipeline operation, the transmission joint can effectively absorb the radial displacement of the pipeline, but it can not absorb the axial displacement of the pipeline. Xinli dismantling double flanges transmission joint can be fitted with ball valve, butterfly valve, check valve and other large valves. It is applicable in power engineering circulating water pipelines, condensing water pipelines, petroleum petrochemical pipelines, sewage treatment pipelines and water supply and drainage pipelines. Xinli transmission joint is also applicable to the corner of large diameter circulating water pipeline, and can effectively compensate the displacement and vibration of the corner pipe, especially the long distance pipeline. Because of the rigid connection, the sealing between flanges is easily affected by the flexibility of the pipeline itself, so use transmission joint can protect the pipeline very well. There is a good compensation and release space when the pipeline in the cold and hot deformation.

Dismantling double flanges transmission joint made of metal casting or welding, and the loose sleeve part is made of trapezoidal rubber seal gasket. Under the action of cover and bolt, using the principle of rubber compression elastic deformation, the sealing gasket is forced to be deformed between the outer wall of the telescopic tube of the joint body for static sealing. Metal and sealing gaskets are strictly selected in accordance with performance and user requirements. External coating high-strength anticorrosive paint, each part of connection bolts for 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 transmission joints can effectively compensate and relieve the thrust of the pipe and the blind plate in the pipeline. It can also be convenient for the installation, maintenance and replacement of pumps and valves, which is the most ideal supporting product in pipeline installation and transportation industry.
