Flange detachable dowel joint can be equipped with ball valve, disc valve, check valve, down large valve, such as in power engineering circulation pipe, condensed water pipe, petroleum and petrochemical pipeline, sewage pipes and water supply and drainage pipeline applies for large diameter dowel joint the corner of the circulating water pipes also apply, can not effectively compensate the corner pipeline for displacement and vibration, especially in long distance pipeline, because of the rigid connection between the flange sealing easily influenced by the pipe varicose sex itself, so use dowel joint can very good protection pipes, pipe in cold and hot deformation, has good compensation and free space.

Installation instructions: Double flanged loose sleeve force transfer joint is suitable for connecting with flange on one side and welding with pipe on the other side. During installation, adjust the installation length of both ends of the product and the pipe or flange. After installation and welding, screw down the gland bolt evenly once to make it a whole with certain displacement, which is convenient for installation and maintenance. It can be adjusted according to the field size. Axial thrust can be transmitted throughout the pipeline during operation. Detachable double flange joint force is mainly on the basis of the original double flange joint force increased the spool flange, is specially developed for the installation of the valve to remove pipe fittings, in the process of the lifting of heavy especially ball valve valve by adjusting the length of the double flange joint force of the gap between the valve in the pipeline, with the valve after the hoisting control limit dowel joint bolt elongation can be better to install the valve, dowel joint in the process of pipeline operation can effectively absorb piping of radial displacement but axial displacement of the pipeline cannot be absorbed.
