Stainless Steel Pipe Factory: Dual-Pressure Stainless Steel Pipe Fittings

- Apr 04, 2018-

Double-push-type stainless steel pipe fittings are provided with a joint body and an annular convex portion and a hole in the groove are provided with a seal ring at a certain distance from the port; the inner body of the joint is provided with a positioning step for inserting a steel pipe; and the diameter and the contact of the joint body with water are provided. The steel pipe remains unchanged or/and transitions smoothly. When installing, it only needs to use a special tool card to press the pressure on both sides of the convex part, and the joint body wall and the deformed pressure and pressure of both sides of the steel pipe and the seal ring are integrated, and the strength of the standard single card pressure pipe fitting of stainless steel pipe is doubled. The sealing performance is greatly improved and the test pressure is up to 10 MPa. During work, the flow path of the joints remains unchanged and the water resistance is not increased. This prevents the deposition of water slag from corroding the fittings and does not affect the water quality. Positioning steps, so that the pipe limit size is a fixed value, the pipe size calculation is accurate and easy to install. And the overall structure is simple, the price of stainless steel is less expensive, and the cost is greatly reduced.

Double card type stainless steel pipe fittings

A double-push-type stainless steel pipe has a connecting body (1) on which an annular convex portion (1.1) is provided, and a groove (2) having a shape matching with the convex portion is arranged in the groove in the annular convex portion, and the annular convex portion is provided. The position is located within the connecting section (X1) of the connecting body (1) and the stainless steel pipe (3) to be connected, and the annular projection has a certain distance (X) from the position of the connecting port (1.3); A. The annular protrusion is provided on the connecting body at each port (X); B. In the connecting body bore is provided with a positioning step (1.2) cooperating with the end of the connected steel pipe; C. In the connecting body, the over flow diameter (D1) of the non-joint section (X2) between the steel pipes and the steel pipe (3) through flow diameter (D2) remain unchanged or/and the smooth transition (1.4c), (1 .4d).
