Butt Welding Fitting A269 WP321 Reducing Tee 4X2 Stainless Steel ASME B16.9

Butt-Welding Fitting A269 WP321 Reducing Tee 4*2 Stainless Steel ASME B16.9

The tee is a pipe fittings and pipe connection. Also called pipe fittings tee or tee pipe fittings,

tee joints, used in the main pipeline to branch pipe.
The tee has three openings, that is, one import and two exits; Or two inlets, one outlet of a

chemical pipe fittings, there are T-shaped and Y-shaped, there are equal diameter pipe mouths,

there are also different diameter pipe mouths, used for the convergence of three identical or

different pipelines. The main function of the tee is to change the direction of the fluid.

Divided by pipe diameter size
The nozzle ends of the equal-diameter tees are all the same size;
The main pipe size of the reducer tee is the same, while the pipe size of the branch pipe is

smaller than the pipe size of the main pipe.
Divided by process
1. Hydraulic expansion
The hydraulic expansion of the tee is a forming process in which the branch pipe is compensated

by the axial direction of the metal material. The process is to use a special hydraulic press, and

the three-way diameter equal to the pipe blank injected liquid, through the hydraulic press two

horizontal side cylinders synchronous alignment movement to extrude the pipe blank, the volume

of the pipe blank after being squeezed becomes smaller, the liquid in the pipe blank with the

volume of the pipe blank becomes smaller and the pressure rises, when the pressure required

for the expansion of the tee branch pipe is reached, the metal material flows along the mold

cavity under the dual action of the side cylinder and the liquid pressure in the pipe blank and

expands the branch pipe.
The hydraulic expansion process of the tee can be formed at one time, and the production

efficiency is high; The main and shoulder wall thickness of the tee has increased.
Due to the large tonnage of equipment required by the hydraulic expansion process of seamless

tee, it is mainly used in the manufacture of standard wall thickness tees smaller than DN400

in China. Its applicable forming materials are low carbon steel, low alloy steel, stainless steel

with relatively low cold work hardening tendency, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc.
