When construct the flexible rubber joint,it is necessary to make it in the natural state, and do not cause the deformation out of the product.
1,when the pipeline medium is acid and alkali,oil,high temperature and other special materials should be used higher than the working pressure of the joints.
2,connecting the flange of the rubber joints shall be the valve flange or GB/T9115.1 (RF) of the flange.
3,rubber joint normal applicable medium is ordinary water,temperature is 0-60 degrees C, special medium such as oil,acid and alkali, high temperature and other corrosion and texture hard situation should be selected relative deserve special refractory material.
4,flexible rubber flexible connector use in the outlet of the pump should be at the side of a fountain,and springs of water should be installed metal reducer union and installed in the diameter of the large diameter provenance.
5,when the pipeline displacement is greater than or equal to the maximum amount of compensation,it should increase the number of joints to parallel displacement,is strictly prohibited in order to adjust the pipe,so that the joints are in the limit of deflection and deviation state,but can not be overrun, displacement,deflection, etc..
6,high water or suspension of water supply,the pipe should be fixed on the hanger, bracket,or anchor frame,and not allow joint channels to withstand its own weight and axial force,otherwise the connector should be equipped with anti pull off device.
7,the installation of rubber joints,bolts should be extended to the joints of the joints, each of the flange end face of the bolt by the method of repeated uniform and evenly tightened,to prevent the pressure.
8, the rubber soft joints in the first time after the initial pressure to bear or disable again,should be re tightened and then put the bolts and then put into operation.
