Pipe Fittings Pipe Connections Stainless Steel Tee

The tee is a pipe fittings and pipe connection. Also called pipe fittings tee or tee pipe fittings, tee joints, used in the main pipeline to branch pipe. The tee has three openings, that is, one import and two exits; Or two inlets, one outlet of a chemical pipe fittings, there are T-shaped and Y-shaped, there are equal diameter pipe mouths, there are also different diameter pipe mouths, used for the convergence of three identical or different pipelines. The main function of the tee is to change the direction of the fluid.  Divided by pipe diameter size The nozzle ends of the equal-diameter tees are all the same size; The main pipe size of the reducer tee is the same, while the pipe size of the branch pipe is smaller than the pipe size of the main pipe. Divided by process 1. Hydraulic expansion The hydraulic expansion of the tee is a forming process in which the branch pipe is compensated by the axial direction of the metal material. The process is to use a special hydraulic press, and the three-way diameter equal to the pipe blank injected liquid, through the hydraulic press two horizontal side cylinders synchronous alignment movement to extrude the pipe blank, the volume of the pipe blank after being squeezed becomes smaller, the liquid in the pipe blank with the volume of the pipe blank becomes smaller and the pressure rises, when the pressure required for the expansion of the tee branch pipe is reached, the metal material flows along the mold cavity under the dual action of the side cylinder and the liquid pressure in the pipe blank and expands the branch pipe. The hydraulic expansion process of the tee can be formed at one time, and the production efficiency is high; The main and shoulder wall thickness of the tee has increased. Due to the large tonnage of equipment required by the hydraulic expansion process of seamless tee, it is mainly used in the manufacture of standard wall thickness tees smaller than DN400 in China. Its applicable forming materials are low carbon steel, low alloy steel, stainless steel with relatively low cold work hardening tendency, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc. 2. Hot press forming Cold-drawn tee Cold-drawn tee Tee hot pressing is to flatten the pipe blank larger than the diameter of the tee to the size of the tee diameter, and make a hole in the part of the stretched branch pipe; The pipe blank is heated, put into the forming die, and the die of the stretched branch pipe is loaded into the pipe blank; Under the action of pressure, the pipe blank is compressed radially, and in the process of radial compression, the metal flows in the direction of 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 pipe blank and the stretching process of the branch pipe part. Unlike hydraulic expansion tees, the metal of hot-pressed tee branch pipes is compensated by the radial movement of the pipe blank, so it is also called a radial compensation process. Due to the use of pressed tees after heating, the tonnage of equipment required for material forming is reduced. The hot-pressed tee has wide adaptability to the material and is suitable for materials of low carbon steel, alloy steel and stainless steel; In particular, tees with large diameters and thick walls are usually formed in this way.
