Straight through plate sleeve joint
Description
The sleeve joint has the characteristics of strong connection, high pressure resistance, temperature resistance, good sealing and repetition, convenient installation and maintenance, safe and reliable work. Its working principle is to insert the steel pipe into the sleeve, using the nut of the sleeve to lock, resist the sleeve, cut into the pipe and seal. It does not need to be welded when connected with the steel pipe, which is conducive to fire prevention, explosion-proof and high-altitude operation, and can eliminate the disadvantages brought by careless welding. So it is refining, chemical, petroleum, natural gas, food, pharmaceutical, instrument and other systems automatic control device pipeline in a more advanced connection. Suitable for oil, gas, water and other pipeline connection.

Overview of sleeve joints
Sleeve type pipe joint consists of three parts: joint body, sleeve, nut. When the sleeve and nut sleeve are inserted into the joint body on the steel pipe and the nut is tightened, the outer front end of the sleeve is fitted with the conical surface of the joint body, and the inner edge bites into the seamless steel pipe evenly to form an effective seal.
The W end of the 24° cone is according to DIN 3861. The sleeve is double-edged.
Usually the surface of the joint body and nut is galvanized. The working pressure of the joint is up to 63MPa, and the outer diameter of the seamless steel pipe is 42mm.
