橡胶接头根据管道内介质的不同来选用不同的材质，例如耐高温用三元乙丙橡胶接头，耐酸碱用氯丁橡胶接头，耐油用氢化丁晴橡胶接头等。 Introduction: Rubber joints are made of different materials according to the medium in the pipeline, such as high temperature resistant EPDM joints, acid and alkali resistant neoprene joints, and oil resistant hydrogenated butadiene rubber joints. However, it will also encounter strong acid, strong alkali and strong high temperature. At this time, more special materials will be used. Fluorine rubber will be used at ultra-high temperature, and PTFE-lined joints will be used in strong acid environment.
Rubber joints are
made of different materials depending on the medium in the pipeline, such as ethylene-propylene-diene rubber joints for high temperature resistance, neoprene joints for acid and alkali resistance, and hydrogenated butadiene rubber joints for oil resistance. However, it will also encounter strong acid, strong alkali and strong high temperature. At this time, more special materials will be used. Fluorine rubber will be used at ultra-high temperature, and PTFE-lined joints will be used in strong acid environment. The following introduces the specific situation of PTFE-lined joints.
Because rubber, glass, metal alloys and other materials have defects in corrosion resistance, it is difficult to meet harsh conditions such as temperature, pressure, and coexistence of chemical media, and the losses caused by this are quite amazing. PTFE material has relieved this phenomenon with its excellent corrosion resistance, and it has also become the main corrosion resistant material in petroleum, chemical, textile and other industries. Its specific applications include: transportation pipes, exhaust pipes, steam pipes for transporting corrosive gases, high-pressure oil pipes for rolling mills, high-, medium-, and low-pressure pipes for aircraft hydraulic systems and cold-pressing systems, distillation towers, heat exchangers, kettles, towers, and tanks Linings, valves and other chemical equipment.
PTFE-lined flexible rubber joints are added with PTFE.TEFLON polytetrafluoroethylene coating on the basis of general rubber joints or EPDM high-wear rubber joints. The coating is mainly white, which can effectively protect the rubber. The joints are not corroded by corrosive media such as strong acids, alkalis or high temperature oils. The original mechanical and physical properties of the flexible rubber joints have not been affected, and they can still compensate for pipeline vibration and absorb pipeline displacement to reduce pipeline noise. The polytetrafluoroethylene coating can effectively adhere to the inner wall of the pipe to prevent it from being washed away by the medium or the pipe is stretched and contracted to cause detachment. Our company's PTFE-lined flexible rubber joint originally used high-quality raw rubber imported from Malaysia. The PTFE.TEFLON material is South Korea's Samsung Chemical products, high purity without any impurities, the use of advanced coating technology, the plastic and rubber matrix hot-melt combination to make the coating and rubber base into one, enhance the coating adhesion, so that the product has a good Corrosion resistance and impact resistance; the coating surface is smooth, the friction coefficient is small, the non-adhesion is strong, and the resistance to foreign matter is excellent; the coating is non-toxic, solvent-free, exudate-free, does not pollute the medium, and is more suitable for sanitary conditions Highly demanding pharmaceutical, beverage, food, brewing and chemical, power industry, and environmental desulfurization industry.
