Definition of Tee C*C*C
The tee joint is a kind of pipe fittings, and its connection form is to directly butt weld the tee with the steel pipe.
Classification of Tee
1. According to the diameter of the pipe fittings, there are generally equal diameter tees, reducing tees, etc.
2. According to the branch direction, there are positive three links and oblique three links.
3. According to the material, there are three links such as carbon steel, alloy steel, stainless steel, copper, and pvc.
4. According to the connection mode, there are ordinary tee, threaded tee, ferrule tee, and socket tee.
Divided by material
Carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leaching, pvc, etc.
Divided by production method
Topping, pressing, forging, casting, etc.
The production process of the three links
Tee forming is to squash the tube blank larger than the diameter of the tee to the size of the tee diameter, and open a hole in the stretched branch tube; the tube blank is heated, put into the forming mold, and put into the tube blank The die for stretching the branch pipe; the tube blank is radially compressed under the action of pressure, and the metal flows in the direction of the branch pipe during the radial compression process and forms the branch pipe 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 tube. Different from the hydraulic bulging tee, the metal of the branch pipe of the tee joint is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.As the tee is pressed after heating, the tonnage of equipment required for material forming is reduced. Hot-pressed tee has a wide adaptability to materials, and is suitable for low-carbon steel, alloy steel, and stainless steel; especially for tee with large diameter and thicker tube wall, this forming process is usually used.
