Pipe fittings tee fittings accessories introduction

The tee joint is a kind of pipe fitting, and its connection form is to directly butt weld the tee and the steel pipe. Mainly classified according to the following:
1. According to the caliber of pipe fittings, there are generally equal diameter tees and different diameter tees.
2. There are positive tees and oblique tees according to the direction of the branch pipe.
3. According to the material, there are carbon steel, alloy steel, stainless steel, copper, PVC and other three links.
4. According to the connection method, there are ordinary tee, thread tee, ferrule tee and socket tee.
5. The tee representation method is as follows: For the equal diameter tees, such as "T6" tees represent equal diameter tees with an outer diameter of 6 inches.

By material
Carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, pvc, etc.

According to the production method
Pressing, pressing, forging, casting, etc.
Three-way joint forming is to crush the tube blank larger than the diameter of the three-way pipe to the size of the three-way diameter, and make a hole in the stretched branch pipe; the tube blank is heated, put into the forming die, and installed in the tube blank Into the die of the drawing branch pipe; under the action of pressure, the tube blank is compressed radially. During the process of radial compression, the metal flows toward the branch pipe and forms the branch pipe under the drawing 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 expansion tee, the metal of the tee joint branch pipe is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.

Because the tee is pressed after heating, the tonnage of the equipment required for material forming is reduced. Hot-pressed tees have a wide adaptability to materials, and are suitable for low-carbon steel, alloy steel, and stainless steel materials; especially tees with large diameters and thick pipe walls, this forming process is usually used.
