SCH10S A403 WP316 GB/T10002.2 304 Stainless Steel Pipe Tee Fittings

Tees are pipe fittings and pipe connectors. Also known as pipe fittings tee or tee fittings, tee joints, used in the main pipe to branch pipe, change the direction of the fluid.

By process:

1. Hydraulic bulging

Hydraulic bulging of tee is a forming process of branch pipe by axial compensation of metal material. 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. After being extruded, the volume of the tube blank becomes smaller, and the pressure of the liquid in the tube blank increases with the decrease of the tube blank volume. When the pressure required for the expansion of the tee branch pipe is reached, the liquid pressure of the metal material in the side cylinder and tube blank is double The lower branch pipe is expanded out of the cavity and flows along the mold.

2. Hot pressing

Hot pressing forming of tee is to flatten the tube blank larger than the diameter of tee, flatten it to the size of tee diameter, and open a hole in the part of the stretching branch pipe; the tube blank is heated and put into the forming die and then put into the punching die of the stretch branch pipe; under the pressure, the tube blank is compressed radially, and the metal flows towards the branch pipe in the radial compression process and forms the branch pipe under the drawing of the punch. The whole process is formed by radial compression of tube blank and stretching process of branch pipe. Unlike the hydraulic expansion tee, the metal of the hot pressing tee is compensated by the radial motion of the tube blank, so it is also called radial compensation process.

The tonnage of equipment needed for material forming is reduced because of the pressing tee after heating. Hot pressing tee is widely used for materials of low carbon steel, alloy steel and stainless steel, especially for the tee with large diameter and thick pipe wall, which is usually used in this forming process.
