Classified by pipe diameter:
The nozzle ends of equal diameter tees are of the same size;
The main pipe size of the reducing tee is the same, while the branch pipe size is smaller than the main pipe size.
By process
1. Hydraulic bulging
Hydraulic bulging of tees is a forming process that expands branch pipes through axial compensation of metal materials. The process is to use a dedicated hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and press the tube blank through synchronous centering movement of the two horizontal side cylinders of the hydraulic press. The volume of the tube blank becomes smaller after being squeezed, and the pressure of the liquid in the tube blank increases as the volume of the tube blank becomes smaller. When the pressure required for the expansion of the tee branch pipe is reached, the metal material flows along the inner cavity of the mold and expands out of the branch pipe under the dual action of the side cylinder and the liquid pressure in the tube blank.
The hydraulic bulging process of the tee can be formed in one step, with high production efficiency; The wall thickness of the main pipe and shoulder of the tee increases.
Due to the large tonnage of equipment required for the hydraulic bulging process of seamless tees, it is mainly used in the manufacturing of standard wall thickness tees smaller than DN400 in China. The suitable 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, and titanium.
2. Hot pressing forming
Cold drawn tee
Cold drawn tee
Hot pressing of a tee involves flattening a tube blank larger than the diameter of the tee to about the size of the tee diameter and opening a hole in the part where the branch pipe is stretched; The tube blank is heated, placed into a forming die, and a stamping die for drawing the branch pipe is inserted into the tube blank; Under the action of pressure, the tube blank is compressed radially. During the radial compression process, the metal flows in the direction of the branch pipe and forms a branch pipe under the drawing of the die. The entire process is formed through the radial compression of the tube blank and the stretching process of the branch pipe. Unlike hydraulic bulging tees, the metal of hot pressed tees is compensated by the radial motion of the tube blank, so it is also known as a radial compensation process.
Due to the use of heated and pressed tees, the tonnage of equipment required for material forming is reduced. Hot pressed tees have a wide range of adaptability to materials, suitable for low carbon steel, alloy steel, and stainless steel materials; Especially for tees with large diameters and thick pipe walls, this forming process is commonly used.
