rubber joints are use cartons for shipping,in order to protect the flange and the sphere, soft rubber joints installation method:
1 rubber soft joints in the first bear the pressure (such as: after the installation of pressure, etc.) or long-term disable again before the start, should be re tightened the bolt and then put into operation.
2 when the pipeline produces instantaneous pressure and is greater than the working pressure should be higher than the working pressure of a gear. (for example, when the pipeline starts an instantaneous pressure >1.0MPa, the joint shall be used for 1.6MPa. In the instant pressure >1.6MPa, the 2.5MPa of the joints should be selected.
3 when the pipeline medium for acid and alkali, oil, high temperature and other special materials should be used to work more than the pipeline pressure of a file.
4 connecting the flange of the rubber soft joint shall be the valve flange or GB/T9115.1 (RF).
5 soft rubber joints normal for medium temperature in 0-60 deg.c ordinary water, special medium such as oil, acid and alkali, high temperature and other corrosion and texture hard situation should be selected corresponding Tenai materials rubber joints, not blindly on or universal.
6 soft rubber joints use in the outlet of the pump shall be located in one side of the water pump, and between the pump should be installed metal reducer union and installed in the large aperture diameter.
7 use or storage of rubber soft joints, should avoid high temperature, ozone, oil and acid and alkali environment. Used in the pipeline or outdoor Xiangyang windward should build a sunshade frame, from the sunlight, rain, wind erosion. The surface of the rubber soft joint is strictly forbidden to brush the paint and the winding insulation material. Because of the aging of rubber products, the replacement should be checked in time.
8 high water, 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 (the bearing capacity must be larger than that of the pipe axial).
9 when installing rubber soft joints, the bolts should be extended to the outside of the joints, and the bolts of the end face of each flange are repeatedly tightened and tightened, and the pressure is prevented. Wire joint should use the standard uniform wrench tightening force, don't with afterburner afterburner par the union silky, smooth edge and fracture, but also to regularly check, lest cause loosening off disk or seepage.
10 must be based on the work of the pipeline pressure, connection mode, medium and the amount of compensation to choose the right model, the number of rubber joints.
