are hollow rubber products used for flexible connection between metal pipes. It consists of inner and outer layers of rubber, ply and traveller, which form a tubular rubber piece. After vulcanization, it is combined with metal flange or parallel joint loose sleeve. Not only can it reduce vibration and noise, but it can also compensate for thermal expansion and contraction caused by temperature changes. It is widely used in various pipe systems.
The rubber joints are all made of imported rubber, which has the characteristics of corrosion resistance, temperature resistance and wear resistance. It plays an important role in ensuring the long-term safe operation of the pipeline. During the installation of the rubber joint, the rubber part must be buckled into the groove of the flange well, so that the anti-flange can press the rubber end face well after installation and use, and there will be no leakage during use. When a leak occurs, some installers think that tightening the bolts will not leak. This is wrong. Tightening the bolts strongly will crush the sealing surface of the rubber edge, so that the sealing surface breaks, and the rubber ball part is scrapped. Forging Generally, flanges have lower carbon content than cast flanges and are less prone to rust. The forgings are more streamlined and denser in structure. The mechanical properties are better than those of casting flanges. Improper forging process can also cause large or uneven grains, and hardening cracks. Cast flange. Forgings can withstand higher shear and tensile forces than castings. The advantages of castings are that they can achieve a more complex shape and lower cost. The advantages of forgings are that the internal structure is uniform, and there are no harmful defects such as pores and inclusions in the castings. Therefore, it is recommended to use forging flanges in high pressure working situations , More use to prevent the leakage of rubber joints. Rubber joints are mainly used for long-distance pipe compensation connections, which have the characteristics of compensation for displacement and vibration reduction and noise reduction. Rubber joints can be used in water supply and drainage pipes, seawater desalination pipes, ship pipes, fire protection pipes, sewage treatment pipes, etc.
