Product details

The double flanged force transfer joint is composed of flanged loose sleeve expansion joint, short pipe flange, force transfer screw and other components. By connecting the joint as a whole through a long stud, it can reduce the pressure thrust (blind plate force) of the connected part and compensate the installation error of the pipeline, mainly solve the connection between the pump, valve and other equipment and the pipeline. During the installation and maintenance of equipment and pipes, the installation size can be flexibly adjusted according to the site conditions. During normal operation, the axial push force can be transmitted to the entire pipeline to protect the safety of the pump and valve. This series of products are widely used in urban water supply and drainage, sewage treatment and other industries of fluid transmission pipeline.



Product characteristics

1, flexible, safe limit, reliable sealing, convenient loading and unloading structure is reasonable, simple and compact, reliable sealing performance;

2, not affected by space, can be installed in any position of the pipeline;

3, Transfer axial push force to protect pipe network and equipment safety;

4, the connecting parts are made of stainless steel, the body is sprayed with epoxy resin, and the anti-corrosion effect is good.
