Tees, also known as pipe fittings or tee fittings, tee joints, etc. Mainly used to change the direction of the fluid, used at the main pipeline or branch pipe. It can be classified by pipe diameter size. Generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon carbide, PVC, and other materials.
Tees are pipe fittings and pipeline connectors. Also known as a pipe fitting tee or tee fitting, a tee joint is used where the main pipeline needs to branch. A tee has three openings, one inlet and two outlets; A type of chemical pipe fitting with two inlets and one outlet, consisting of T-shaped and Y-shaped fittings, with equal diameter nozzles and reducing diameter nozzles, used at the confluence of three identical or different pipelines. The main function of a tee is to change the direction of the fluid.
Divided by pipe diameter size
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.
Divided by process
1. Hydraulic bulging
Hydraulic bulging of tees is a forming process that uses axial compensation of metal materials to expand branch pipes. The process involves using a dedicated hydraulic press to inject liquid into a tube blank with a diameter equal to the diameter of the tee. The tube blank is compressed through two horizontal side cylinders of the hydraulic press, which move synchronously to the center. The volume of the tube blank decreases after compression, and the pressure inside the tube blank increases as the volume of the tube blank decreases. 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 pressure of the side cylinder and the liquid inside the tube blank.
The hydraulic bulging process of the tee can be formed in one go, resulting in high production efficiency; The main pipe and shoulder wall thickness of the tee have increased.
Due to the large tonnage of equipment required for the hydraulic expansion process of seamless tees, it is mainly used in the manufacturing of standard wall thickness tees less than DN400 in China. The suitable 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.
2. Hot pressing forming
Tee hot pressing forming is the process of flattening a tube blank larger than the diameter of the tee to a size approximately equal to the diameter of the tee, and opening a hole in the area where the branch pipe is stretched; The tube blank is heated and placed in the forming die, and a stamping die for stretching the branch pipe is inserted into the tube blank; Under the action of pressure, the tube blank is radially compressed, and during the radial compression process, the metal flows in the direction of the branch pipe and forms a branch pipe under the stretching 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 expansion tees, the metal of hot pressed tees is compensated by the radial motion of the pipe blank, so it is also known as the 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 adaptability to materials and are suitable for materials such as low-carbon steel, alloy steel, and stainless steel; Especially for tees with large diameters and thick pipe walls, this forming process is usually used.
