The processing technology of pipe fittings tee -- hot pressing

　　Stainless steel tee hot forming is a tube billet larger than stainless steel tee through diameter, which is compressed into a diameter of three through a hole in the part of a stretch branch; the tube is heated to be put into a forming die and is loaded into a drawing die; the tube is compressed in radial direction under the action of pressure, and in the process of radial compression, the metal is directed to the branch. The tube flows and forms a branch under the drawing of the die.

　　The whole process is formed by the radial compression of the billet and the drawing process of the branch. Unlike the hydraulic bulging stainless steel tee, the metal of the hot pressing stainless steel tee is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.

　　Due to the use of heating to suppress stainless steel tee passes, the equipment tonnage required for material forming is reduced. The stainless steel tee hot press is suitable for the material with wide adaptability to low carbon steel, alloy steel and stainless steel, especially for the three through thick diameter and tube wall, which is usually used in this forming process.
