Stainless steel sleeve pipe joint is a new type of pipe connecting element.

Advantage

1. The structure is simple, the sealing performance is reliable, the use is convenient, the manufacture is excellent, the appearance is light and beautiful.

2. Do not have to add the washer, do not have to weld, save material, the performance is good again and again.

3. Because the stainless steel sleeve pipe joint can not be welded, the influence of the pipeline impurities on the performance of the system is reduced. Therefore, the stainless steel sleeve pipe joints are increasingly widely used in the oil, gas, hydraulic and pneumatic equipment for the media pipeline, especially for the burning of dangerous, high altitude operations and installation and demolition of frequent occasions. It has been vigorously promoted and used in our country.

Structure and principle

1. The basic structure of the joint is relatively simple, and only the connector body, the clamping sleeve and the nut are composed of three basic components. One of the main parts is a card sleeve, which is a front end with the edge of the metal ring. International standard GB3764-83 on the edge of the blade is recommended for the I shape.

2. This joint play a major role in sealing the other piece of card sets, the axial force plays a role in R nut compaction under the axial movement along the inner taper hole of the joint body, and the blade end to produce radial shrinkage in the radial force under the action of R', to eliminate the gap and the pipe sleeve, and a cutting edge contact the surface of the tube, the tube is no longer rotating, continues to rotate the nut to make the sleeve edge firmly cut pipe to ensure the sealing. Another aspect is the intersection of the card sealing edge endpoint and chamfer angle of 13 DEG Park (edge) and ring joint body cone close contact to form a seal belt, which is the main part of sleeve type seal. The card sets 86 degrees to produce tail cone radial shrinkage of F under the action of force, to be connected at the same time the central tube, slightly arched, so the ferrule has axial elastic deformation, the sleeve seal and prevent nut loosening were beneficial, can better connect metal pipes.
