The working principle of the ferrule joint is to insert the steel pipe into the ferrule, lock it with the ferrule nut, resist the ferrule, cut into the pipe and seal it. It is connected with the steel pipe without welding, is conducive to fire prevention, explosion-proof and high-altitude operations, and can eliminate the disadvantages of careless welding. Therefore, it is a more advanced connector in the pipeline of automatic control devices of oil refining, chemical, petroleum, natural gas, food, pharmaceutical, instrumentation and other systems. Suitable for oil, gas, water and other pipeline connection. The ferrule type pipe joint consists of three parts: the joint body, the ferrule and the nut. When the clamp sleeve and nut sleeve are inserted into the joint body on the steel pipe, when the nut is tightened, the outer side of the front end of the clamp sleeve is attached to the conical surface of the joint body, and the inner blade evenly bites into the seamless steel pipe to form an effective seal. The ferrule joint has the characteristics of corrosion resistance, high pressure resistance, simple installation and durability. The ferrule type joint has the characteristics of firm connection, high pressure resistance, temperature resistance, good sealing and repeatability, convenient installation and maintenance, safe and reliable work, etc.
