Tube fitting for stainless steel tubing

A two parts matched with the body (54) and matched cap (52) pipe joint (50). Matching cap and matched with body through the rotating relative screw thread in. Matching cap comprising a pipe clamping ring is a integrally formed (80), when the ring of the joint is mounted on the convex (88) and matched body matched. The convex (88) and a better with a convex large angle. Fix the clamping ring (80) is extrusion tube is formed between the sealing and clamping pipe. The clamping ring (80) is (88) of the line contact sealing and convex. The clamping ring of the driving ring type with the rotating and plastic deformation and to the pipe, formed by the rod tube clamp; the clamping ring is provided with an axial adjacent extruded or a pressure area, the area a pressed in any stress elevation and vibration function of the movement of insulation. The two connecting part; the clamping ring, and a heatsink carburizing, particularly the joint capable with automatic control, instructed of a enough type, and is tensed excessively. Featured with single metal pipe joint, comprising a large convex (88), and hardness at least is stainless steel jet degree of the hardness and 3.3 times.
