Threaded rubber expansion joint in doing pipeline connection considerations summary.

When the medium of threaded rubber expansion joint pipeline is acid and alkali, oil, high temperature and other special materials should be selected one grade higher than the working pressure of the pipeline. The threaded rubber joint utilizes the elasticity, high airtightness, media resistance, weather resistance and radiation resistance of rubber, and is made of high strength, cold and heat stable polyester cord fabric twill intersection and its compound, and then vulcanized by high pressure and high temperature mold.
Threaded rubber joints in making pipeline connections should be how to do.
1 . The normal applicable medium for the threaded soft joint is ordinary water at a temperature of 0-60℃, special media such as oil, acid and alkali, high temperature and other corrosive and hard textures should be selected with the corresponding special resistant material rubber joints, not blindly used in series or universal.
2 . When the instantaneous pressure of the pipeline is greater than the working pressure, the joint should be used one grade higher than the working pressure. (For example, if the instantaneous pressure of the pipeline is greater than 1.0MPa, a joint with a working pressure of 1.6MPa should be used. When the instantaneous pressure is greater than 1.6MPa, a joint with 2.5MPa should be used).
3 . When the pipeline displacement is greater than or equal to the compensation amount of the joint, the number of joints should be increased to parallel the displacement amount, and it is strictly forbidden to make the joint in the state of disturbed displacement and deviation in order to adjust the super difference of the pipeline, not to mention the super limit (expansion, displacement, deflection, etc.).
4 . When the pipeline medium is acid and alkali, oil, high temperature and other special materials, the joint should be used one grade higher than the working pressure of the pipeline.
5 . According to the working pressure of the pipeline, connection mode, medium and compensation amount, choose the appropriate model, and its quantity according to the requirements of noise reduction and displacement.
6 . Threaded soft connection used in the pump import and export, should be located near the pump side, and the pump should be installed between the metal reducer joint, and installed in the large diameter of the reducer.
