The rubber joint is generally composed of an inner rubber layer, a fabric reinforced layer (the reinforced layer has a multi-layer scraping nylon cord fabric), a middle rubber layer, an outer rubber layer, and a reinforced metal ring or steel wire ring at the end, which is vulcanized by high temperature and high pressure, and is combined with a metal flange or a parallel joint loose sleeve. This product makes use of the advantages of high elasticity, high gas, medium resistance, weather resistance and radiation resistance of rubber, which can reduce the vibration and noise of the pipeline, and can compensate for the thermal expansion and cold contraction caused by temperature changes.
According to the different media used in the rubber material is also different, there are natural rubber, styrene butadiene rubber, butyl rubber, nitrile rubber, EPDM, neoprene rubber, silicone rubber, fluorine rubber and so on. They have heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance and other functions.
Flexible rubber joint has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, health, water heating, fire protection, power and other basic projects. According to different materials can be made of acid, alkali, corrosion, oil, high temperature, radiation, wear resistance, aging resistance and other varieties, adapt to a variety of media and environment.
