The card sleeve joint has the characteristics of strong connection, high pressure resistance, temperature resistance, good sealing and repeatability, convenient installation and maintenance, safe and reliable work, etc. Its working principle is to insert the steel pipe into the sleeve, using the sleeve nut lock, resist the sleeve, cut into the pipe and seal. It does not need welding when it is connected with steel pipe, which is beneficial to fire prevention, explosion prevention and aerial work, and can eliminate the defects caused by careless welding. Therefore, it is a more advanced connector in the pipeline of automatic control devices for oil refining, chemical industry, petroleum, natural gas, food, pharmaceutical, instrumentation and other systems. Suitable for oil, gas, water and other pipeline connections.

Overview of jacket joint

The sleeve type pipe joint is composed of three parts: joint body, sleeve and nut. When the 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 sleeve is attached to the cone surface of the joint body, and the inner edge is evenly bitten into the seamless steel pipe to form an effective seal.

The w-end of the 24° cone is DIN 3861. The sleeve adopts double blade sleeve.

Usually the joint body and nut surface galvanized treatment. The working pressure of the joint is up to 63MPa, and the outer diameter of the seamless steel tube is 42mm.
