Ferrule joint is composed of three parts: joint body, ferrule and nut. When the ferrule and nut are inserted into the joint body on the steel pipe and the nut is tightened, the outside of the front end of the ferrule fits with the conical surface of the joint body, and the inner edge evenly bites into the seamless steel pipe to form an effective seal.

1. Purpose of ferrule joint: ferrule joint is suitable for pipeline system with oil, gas and water as medium. Applicable pressure range: (g) 25MPa, (J) 40MPa.

2. Features of ferrule joint: ferrule joint has a series of advantages, such as advanced structure, good performance, convenient use, no welding, no piping flaring, etc. Therefore, ferrule joints have been widely used in the hydraulic and pneumatic systems of various machines, but the ferrule manufacturing accuracy of ferrule joints is high. Due to the complex process, it is not suitable for sporadic or small batch manufacturing, and professional production is required.
