Ring pressure connection of stainless steel transition joint
Connection principle: Use radial shortening external force (hydraulic pliers) to clamp the pipe on the pipe, and pass the water stop of the wide-band rubber sealing ring to achieve the connection effect.

Advantages and disadvantages:
1. Complete the thin-walled pipes and fittings to save materials
2. Since a pressure pit is added to the compression type, the connection strength is slightly better than that of the compression type (the interface strength still does not reach 1/2 of the strength of the pipe body)
3. The pipe can't be dismantled
4. Since the pressure pit is annular, the tube is easy to change, which affects the sealing effect.
5. The burrs and burrs on the pipe port will damage the rubber ring and become the risk of water leakage in the future. The principle of groove connection connection: select the nut for tightening the pipe fitting, press the pipe with the convex ring and the pipe fitting axially, and pass the cone The water stop of the type sealing ring can achieve the connection effect.





Advantages and disadvantages:
1. Detachable
2. The pipe equipment adds the process of rolling the concave ring at the pipe end
3. Forged clamps are expensive
4. Cannot be used in pipelines with negative pressure Stainless steel transition joints are widely used in petroleum, chemical, fluid, semiconductor, power, steel, electric power, food bioengineering, pharmaceutical, defense, pulp, aviation, metallurgy and mining industries.

The types of stainless steel transition joints are straight through, 90 degree, 45 degree elbows, as well as tee and cross, ferrule type pipe joints, flared pipe joints and welded pipe joints. The products are mainly used in various hydraulic, smooth and Snap-on connection in liquid systems such as cooling
