A234 Wp91 Unequal Tee 560x75mm X 464x55mm Asme B16.9
Tee is also known as pipe fittings, tee or tee fittings, tee joints, etc.
Mainly used to change the direction of the fluid, used in the main pipe to branch pipe.
Tee is a kind of chemical pipe fitting with three openings, i.e. one inlet and two outlets; or two inlets and one outlet. It has T-shaped and Y-shaped, equal diameter nozzle and reducing nozzle, which is used for the convergence of three identical or different pipelines. The main function of the tee is to change the direction of the fluid.
It can be classified by pipe diameter. Generally, it is made of carbon steel, alloy steel and stainless steel.
By process
1. Hydraulic expansion
Hydraulic expansion of three-way is a forming process of expanding branch pipe by axial compensation of metal material. The process is to use a special hydraulic press to inject liquid into the tube billet equal to the diameter of the three links, and to squeeze the tube billet synchronously through the two horizontal side cylinders of the hydraulic press. The liquid in the tube billet increases with the volume of the tube billet.
The hydraulic expansion process of the three-way can be formed at one time, and the production efficiency is high, and the wall thickness of the supervisor and shoulder of the three-way is increased.
Because of the large tonnage of the hydraulic expansion process of seamless three links, it is mainly used in the manufacture of standard wall thickness three links less than DN400. The suitable forming materials are low carbon steel, low alloy steel, stainless steel, including some non-ferrous metal materials, such as copper, aluminum, titanium and so on.
2. hot pressing
The three-way hot pressing forming is to flatten the tube billet larger than the three-way diameter to the size of the three-way diameter. The tube billet is heated and put into the forming die. Under the action of pressure, the tube billet is compressed radially, and the metal flows in the direction of branch pipe and forms branch pipe under the drawing of punching die. The whole process is formed by the radial compression of the tube billet and the tensile process of the branch pipe. Unlike the hydraulic bulging three-way, the metal of the hot-pressed three-way branch pipe is compensated by the radial motion of the tube billet, so it is also called the radial compensation process.
Due to the use of heating to press the three-way, the material forming equipment tonnage is reduced. The hot-pressing tee has a wide adaptability to the material, which is suitable for low carbon steel, alloy steel and stainless steel, especially for large diameter and thick pipe wall.
