Fire Tee
Tee is also known as tee or tee pipe fitting, tee joint, etc.Mainly used to change the direction of the fluid, used in the main pipe to the branch pipe.It can be classified by diameter.It is generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon mold, PVC and other materials.
The tee is a pipe fitting and pipe connection.Also called pipe fitting tee or tee pipe fitting, stainless steel equal diameter tee tee connector, used in the main pipe to branch pipe.
Three - way is with three openings, namely an import, two exports;Or a kind of chemical pipe fitting with two inlet and one outlet, having a T and Y shape, an equal diameter pipe mouth, and a reducing pipe mouth, used for the convergence of three same or different pipes.The main function of the tee is to change the direction of the fluid.
According to the size of pipe diameter
1. The nozzle ends of equal diameter tees are of the same size;
2. The pipe pipe size of the reducing tee is the same, while the pipe pipe size of the branch pipe is smaller than the pipe size of the pipe.
By process
1. Hydraulic bulging
The hydraulic bulging of three - way is a forming technology which compensates the bulging branch pipe by the axial direction of metal material.The process is to use special hydraulic press, with three links within the tube billet diameter equal injection liquid, through the two horizontal side of the hydraulic cylinder synchronization of the motion of tube billet, billet after squeezed smaller volume, smaller volume of liquid with the tube billet inside the tube billet and pressure, when pressure tee branch pipe bulge out to the metal material in the liquid in the cylinder and the pipe pressure under the dual role of flow along the mold cavity and the branch pipe.
Three - way hydraulic bulging process can be formed once, high production efficiency;The main pipe and shoulder wall thickness have increased.
Due to the large tonnage of equipment required for seamless tee bulging process, it is mainly used for the manufacture of tee with standard wall thickness less than DN400 in China.The suitable forming materials are low carbon steel, low alloy steel and stainless steel with relatively low hardening tendency, including some nonferrous materials, such as copper, aluminum and titanium.
2. Hot pressing
Hot pressing of tee is to flatten the pipe billet larger than tee diameter to the size of tee diameter, and then make a hole in the drawing branch pipe of cold drawing tee.The tube billet is heated, put into the forming die, and in the tube billet is loaded with the drawing die;Under the action of pressure, the tube billet is compressed radially. In the process of radial compression, the metal flows towards the direction of 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 billet and the drawing of the branch tube.Different from the hydraulic bulging tee, the metal of the hot-pressed tee branch pipe is compensated by the radial movement of the pipe billet, so it is also called radial compensation process.
Due to the use of heating pressing tee, the material forming equipment tonnage is reduced.Hot pressing tee has a wide adaptability to materials, suitable for low carbon steel, alloy steel, stainless steel materials;In particular, large diameter and wall thickness of the tee, usually used this forming process.
