Three-way fittings are also known as three-way pipe fittings or three-way pipe fittings, three-way joints, etc. ThenThe classification of three-way connectorsWhich ones are there? Let's have the editor of Weili Huang introduce it to you all. I hope it can be helpful.

The classification of three-way connectors is as follows:

I. Classification by process

1Hydraulic bulging

The hydraulic bulging of three-way fittings is a forming process in which the branch pipes are expanded through axial compensation of metal materials. The process involves using a hydraulic press to inject liquid into a tube blank with a diameter equal to that of the tee. Through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press, the tube blank is squeezed. After being squeezed, the volume of the tube blank decreases. As the volume of the tube blank decreases, the pressure of the liquid inside the tube blank increases. When the pressure required for the expansion of the branch pipe of the tee is reached, Under the dual action of the liquid pressure in the side cylinder and the tube blank, the metal material flows along the inner cavity of the mold and expands out the side tubes.

The hydraulic bulging process of the three-way can be formed in one go, and the production efficiency is relatively high;The thickness of the main pipe and the shoulder wall of the three-way valve has both increased.

Due to the large tonnage of equipment required for the hydraulic bulging process of seamless tees, it is currently mainly used for applications smaller thanDN400The manufacturing of standard wall thickness tees. The applicable forming materials are low-carbon steel, low alloy steel and stainless steel with relatively low cold work hardening tendency, as well as some non-ferrous metal materials such as copper, aluminum and titanium.

2Hot pressing forming

Three-way hot pressing forming is a process where a tube blank larger than the diameter of the three-way is flattened to approximately the size of the three-way diameter, and a hole is made at the position of the stretching branch pipe;The tube blank is heated and placed in the forming die, and the die for drawing the branch pipe is inserted into the tube blank;Under the action of pressure, the tube blank is radially compressed. During the radial compression process, the metal flows towards the branch pipe direction and forms the branch pipe under the stretching of the die. The entire process is formed through the radial compression of the tube blank and the stretching process at the branch pipe part. Unlike the hydraulic bulging tee, the metal of the branch pipe of the hot-pressed tee is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.

Due to the adoption of the heated and then pressed tee, the tonnage of the equipment required for material forming is reduced. Hot-pressed tees have a wide range of material adaptability and are suitable for materials such as low-carbon steel, alloy steel and stainless steel;This forming process is usually adopted for large-diameter tees with relatively thick pipe walls.
