What Is a Tee Joint?

A tee joint is a type of pipe fitting, and its connection form is directly butt-welding the tee to the steel pipe.

Tee joint

1. According to the diameter of pipe fittings, there are generally equal-diameter tees and different-diameter tees.

2. There are positive tees and oblique tees according to the branch pipe direction.

3.Carbon steel, alloy steel, stainless steel,

The tee joint forming is to flatten a tube blank larger than the diameter of the tee to a size of the tee diameter, and open a hole at the position where the branch pipe is stretched; the tube blank is heated, placed in a forming mold, and filled in the tube blank Into the die for drawing the branch pipe; under the effect of pressure, the pipe blank is compressed radially, during the radial compression process, the metal flows to the branch pipe and forms a branch pipe under the stretching of the die. The whole process is formed by the radial compression of the tube blank and the drawing process of the branch pipe. Different from the hydraulic bulging 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 equipment required for material forming is reduced. The hot pressing tee has a wide adaptability to materials, and is suitable for low carbon steel, alloy steel, and stainless steel materials; especially for tees with large diameters and thick wall, this forming process is usually used.
