The ferrule type pipe joint consists of three parts: the joint body, ferrule, and nut. When the clamp and nut are inserted into the joint body on the steel pipe, and the nut is tightened, the outer side of the front end of the clamp fits the conical surface of the joint body, and the inner edge evenly bites into the seamless steel pipe, forming an effec~tive seal. The ferrule joint has the characteristics of corrosion resistance, high pressure resistance, simple installation, and durability.
