China Reducing Tee factory is one type of tee, which includes general equal diameter tee and China Reducing Tee factory. It is widely used in the construction and maintenance of projects in petrochemical, fertilizer, power plants, shipbuilding, papermaking, urban construction and other industries.
1. Hydraulic bulging
China Reducing Tee factory’s hydraulic bulging is a forming process in which branch pipes are expanded by the axial compensation of metal materials. The process is to use a special hydraulic press to inject liquid into the tube blank with the same diameter as the tee, and to squeeze the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press. The volume of the tube blank becomes smaller after being squeezed. The pressure of the liquid increases as the volume of the tube becomes smaller. When the pressure required for the expansion of the three-way branch tube is reached, the metal material flows along the inner cavity of the mold under the dual action of the side cylinder and the liquid pressure in the tube blank to expand the branch tube. The three-way hydraulic bulging process can be formed at one time, and the production efficiency is high.

2. Hot press forming
China Reducing Tee factory hot press forming is to flatten a tube blank larger than the diameter of the tee to the size of the diameter of the tee, and open a hole in the stretched branch tube; the tube blank is heated, put into the forming mold, and The blank tube is loaded with a punching die for stretching the branch pipe; the blank tube is radially compressed under the action of pressure. During the radial compression, the metal flows in the direction of the branch tube and forms a branch tube 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 hot-pressed tee branch 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.
