Single flange limited expansion joint is added limit bolts on the basis of the flange covered compensation joint, the largest scale with double nut locking, the compensation due to the heat bilges cold shrink and ground subsidence caused by pipe spool displacement and bending and eccentric, to protect the valve and other equipment. Single flange limited expansion joint is widely used. The medium can be water, hot water, sewage, oil, including crude oil, fuel, and lubricating oil, and gas transport air, gas, and even dust particles medium small solid particles. Single flange limited expansion joint provides a great deal of convenience for various water and drainage pipeline, the installation of a water tower, water pump, water meter and valve.
Single flange limited expansion joint installation instructions
Single flange limited expansion joint is suitable for one side connected with the flange and the other welded with pipe. When installing, adjust product both ends and flange install length, tighten gland bolts by diagonal in turn evenly method, then adjust limited nut again, so that the pipeline can freely expanse within the scope of scale, locking the expansion amount to ensure the pipeline work safely. It is forbidden to use expansion deformation method to adjust the pipeline installation error, so as not to affect the normal function of the expansion joint, reduce the service life of the components and increase the load of piping, equipment and supporting.
