Description

Tee also known as pipe tee or tee pipe fittings, tee joints, etc. Mainly used to change the direction of the fluid, used in the main pipe to branch. It can be classified by pipe diameter. Generally, it is made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PVC and other materials.Tee is a kind of chemical pipe fitting with three orifices, i.e. one inlet and two outlets, or two inlets and one outlet, with T-shaped and Y-shaped, equal diameter pipe orifices and reducing pipe orifices, which are used for the confluence of three identical or different pipes.Stainless steel butt welding tee is a stainless steel elbow formed by hot pressing or forging. Its connection form is directly butt welding the tee and stainless steel pipe.

Specification

1. The main manufacturing standards of butt welding tee are generally GB / T12459, GB / T13401, ASME b16.9, SH3408, SH3409, HG / T21635, HG / T21631, SY / T0510.

2. Equal diameter tee is a kind of stainless steel butt welding tee. There are general equal diameter tee and reducing tee.

3. It is named because the three ends can be connected with the pipe.

4. At present, there are two kinds of technology commonly used in the manufacture of tee with seamless pipe, i.e. hydraulic bulging and hot pressing.

5. The hydraulic bulging of stainless steel tee is a forming process of expanding branch pipe by axial compensation of metal material.

6. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and extrude the tube blank through two horizontal side cylinders of the hydraulic press synchronously, the volume of the tube blank becomes smaller after extrusion, and the pressure of the liquid in the tube blank increases with the volume of the tube blank becoming smaller.

7. When the pressure required by the expansion of the stainless steel tee branch pipe is reached, the liquid pressure of the metal material in the side cylinder and the tube blank is Under the double action of the force, the branch pipe flows along the inner cavity of the die and expands.

Characteristic

1. The hydraulic bulging process of stainless steel tee can be formed in one time with high production efficiency; the wall thickness of main pipe and shoulder of stainless steel tee is increased.

2. Due to the large tonnage of equipment required for the hydraulic bulging process of stainless steel tee, it is currently mainly used for the manufacture of stainless steel tee with standard wall thickness less than dn400 in China.

3. The applicable forming materials are low carbon steel, low alloy steel and stainless steel with relatively low cold work hardening tendency, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc.

4. The extruding deformation of stainless steel butt welded equal tee belongs to elongation deformation. When it is large to a certain extent, the material will produce necking at the edge of the hole, and then crack.

5. Therefore, the main problem of extrusion forming is to prevent the edge of the hole from cracking, and the ultimate deformation degree of one-time extrusion is mainly limited by the elongation of stainless steel.
