Copper Alloy Tee MIM Parts

Product Description

Stainless steel equal diameter tee

The tee is a pipe fitting and a pipe connector. Also known as pipe fittings tee or tee fittings, tee joints are used at the branch pipes of the main pipeline.

Tee is a chemical pipe fitting with three openings, namely one inlet and two outlets; or two inlets and one outlet. The confluence of three identical or different pipelines. The main function of the tee is to change the direction of the fluid.

• Divided by pipe diameter

The ends of the equal diameter tees are all the same size;

The size of the main pipe connection of the tee with different diameters is the same, and the connection size of the branch pipe is smaller than that of the main pipe.

• By process

1. Hydraulic bulging

The hydraulic bulging of the tee is a forming process that expands the branch pipe through the axial compensation of the metal material. The process is to use a special hydraulic machine to inject liquid into the tube blank with the same diameter as the tee, and squeeze the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic machine. After the tube blank is squeezed, the volume becomes smaller, and the tube blank The pressure of the liquid increases as the volume of the tube blank decreases. When the pressure required for the expansion of the tee branch is reached, the metal material flows along the inner cavity of the mold under the dual action of the liquid pressure in the side cylinder and the tube blank to expand the branch tube.

The hydraulic bulging process of the tee can be formed at one time, and the production efficiency is high; the wall thickness of the main pipe and the shoulder of the tee are increased.

Due to the large tonnage of equipment required for the hydraulic bulging process of seamless tees, it is mainly used in the manufacture of standard wall thickness tees less than DN400 in China. Its suitable forming materials are low-carbon steel, low-alloy steel, and stainless steel with relatively low cold hardening tendency, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc.

2. Thermoforming

Cold drawn tee

Tee hot press forming is to flatten the tube blank larger than the diameter of the tee to the size of the tee diameter, and open a hole at the part of the stretched branch pipe; the tube blank is heated, put into the forming die, and the tube blank A die for stretching branch pipes is installed inside; 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 pipes and forms branch pipes under the stretching of the die. The whole process is formed by the radial compression of the tube blank and the stretching process of the branch pipe. Different from the hydraulic bulging tee, the metal of the hot-pressed tee branch is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.

Due to the use of heated and pressed tees, the tonnage of equipment required for material forming is reduced. The hot-pressed tee has a wide adaptability to materials, and is suitable for low-carbon steel, alloy steel, and stainless steel; especially for tees with large diameters and thick pipe walls, this forming process is usually used.
