Tees are also known as pipe tee fittings or pipe tees. A tee joint is used on a branch pipe from the main pipe. It features three openings: one entrance and two exits, or two entrances and one exit. This is a sort of chemical pipe fitting. Pipe fittings come in two shapes: T and Y. There are two types of pipe openings: equal diameters and varying diameters. They change the direction of fluids and are suitable for water pipelines, oil pipelines, and the transportation of various liquid chemical compounds. Pipeline. Main applications include medical, water conservation (water-saving irrigation, water supply and drainage), energy (oil, natural gas, nuclear industry), building, and other engineering sectors.
Jianzhi manufactures a wide range of types of tees, essential components in piping systems that are used to connect three sections of pipe, allowing for the branching or splitting of the flow of fluids.
Classification according to pipe diameter
Equal tee: a tee of the same diameter as the main and branch pipes.
Reducing tee: The diameter of the branch pipe is smaller than that of the main pipe.
Classification according to docking form
Butt welding tee: It is a tee fitting that is welded after being attached to the connecting pipe fitting.
Socket-type tee: It is a tee fitting that is welded or welded after putting the connecting pipe fittings into both ends of the tee.
Tube-type tee: The tube fittings at each end are used to insert and tighten the pipe fitting.
Threaded tee: A tee fitting used to join threaded pipe fittings.
Classification according to material
It can be divided into stainless steel tee, carbon steel tee, copper tee, PVC tee, ductile iron tee, etc.
Classification according to branch pipe form
Positive tee: It is the tee fitting of the vertical main pipe of the branch pipe.
Inclined tee: It is a tee fitting with a specific angle between the branch and main pipes.

4. EU standard: EN10242
5. British Standard: BS1256
6. German standard: DIN2950

Divided by process
Hydraulic bulging involves injecting liquid into a tube blank with the same diameter as the tee and compressing the tube blank using the hydraulic press’s two horizontal side cylinders to center it. After being squeezed, the volume of the tube blank decreases, as does the size of the inside. The pressure of the liquid increases as the tube’s volume decreases. When the pressure required for the tee branch’s expansion is reached, the metal material flows along the inner cavity of the mold, expanding the branch due to the dual action of liquid pressure in the side cylinder and tube.
The hydraulic bulging process for the tee can be completed in a single step, increasing manufacturing efficiency; the wall thickness of the main pipe and shoulder of the tee has been raised.
In hot press forming, the tube blank that is larger than the diameter of the tee is flattened to about the diameter of the tee, and a hole is made in the part where the branch pipe is stretched; the tube blank is heated, placed in the forming mold, and the drawn tube is loaded into it. The die used to expand the branch pipe compresses the tube blank radially under pressure. During the radial compression process, the metal flows in the direction of the branch pipe, forming a branch pipe as the die is stretched. The entire process is generated by radial compression of the tube blank and stretching of the branch tube components.
The use of heated and pressed tees reduces the amount of equipment required for material forming. Hot-pressed tees can be made from a variety of materials, including low carbon steel, alloy steel, and stainless steel; tees with large diameters and thick pipe walls are typically formed using this procedure.
