Extrusion deformation of stainless steel tees pipe fittings belongs to elongation deformation. When ε is large to a certain extent, the material produces neck contraction at the edge of the hole and then cracks. Therefore, avoiding the hole edge break is the main problem of extrusion forming, and the ultimate deformation degree of a extrusion is mainly restricted by the elongation of stainless steel.

Stainless steel tees pipe fittings open process matters needing attention as follows:

1. The ball valve of stainless steel three-way pipe fittings is in the closed position, and the ball is soaked by the mechanical pressure of the stem and pressed tightly on the valve seat.

2. When the hand wheel moves counterclockwise, the stainless steel three-way pipe fitting ball valve stem works in reverse, and its bottom angular plane makes the ball off the seat.

3. The valve stem is drawn continuously and impregnation with the guide pin in the spiral groove of the valve stem to make the ball start to change without conflict.

4. Until it reaches the full open position, the stem is drawn to the limit position and the ball changes to the full open position.
