Rubber joints, also called the soft rubber joints, flexible rubber joints, rubber flexible joints, flexible rubber joints, high-pressure rubber joints, rubber shock absorbers, such as compensation. Press the connection points loose flanges, fixed flanges and threaded three kinds; according to the structure can be divided into five kinds of single ball, double ball, reducers body, bending the ball and pressure plate pipe. The inner and outer layers of plastic, ply and bead composition tubular rubber member vulcanized after forming and metal flanges or parallel connector loose jacket combination. This product can reduce vibration and noise, and thermal expansion and contraction due to temperature changes from the compensation due to the widely used in various piping systems. Rubber joints in the pipe damping effect is obvious. And how pressure rubber joint performance? Pipeline Equipment Factory of Gongyi City Aerospace today to do some experiments: DN150 * 1.6Mpa pressure test pressure test process: 1 ready to try a manual test press pressure used, blind flanges, rubber joints and other tools. 2. Place the buckle on the sphere flange, blind flange and bolted good. (Blind flange and bolt holes are the same) 3. Connect manual test press, add water pressure. The pressure to PN1.0MPa pressure when stopped for five minutes, and observe whether the water leakage. 5. If there is no water leakage, then weighed to PN1.6Mpa pressure, stopped for five minutes and observe. 6. Observe the soft rubber joints not leaking, successful pressure test. Gongyi Yu Hang Pipeline Equipment Factory has a separate mixing plant, the ball molding workshop, product testing storage workshop generated from the production of raw materials to finished products have a strict technical requirements, Gongyi Yu Hang pipeline equipment plant in accordance with customer demand, customized production of special ball (oil , heat, acid, corrosion resistance, abrasion resistance, desulfurization balls, etc.), aerospace people welcome you to visit our factory!
