1. Hydraulic bulging
Three - way hydraulic bulging is a forming process of expanding branch pipe by axial compensation of metal material.The process is to use a special hydraulic machine, and the diameter of the tee tube blank is equal to the injection of liquid, through the two horizontal side cylinders of the hydraulic machine synchronous movement of extrusion tube blank, the volume of the tube blank after extrusion becomes smaller, the liquid in the tube blank with the tube blank volume becomes smaller and the pressure increases, when reaching the three-way branch pipe expansion required pressure,Under the double action of liquid pressure in side cylinder and tube billet, the metal material flows along the inner cavity of mould and expands out the branch tube.
The hydraulic bulging process of tee can be formed at one time, and the production efficiency is higher.The head and shoulder wall thickness of tee were increased.
Due to the large equipment tonnage required by the hydraulic bulging process of seamless tee, it is mainly used for the manufacture of standard wall thickness tee less than DN400 in China.Its suitable forming materials for cold hardening tendency is relatively low low carbon steel, low alloy steel, stainless steel, including some non-ferrous metal materials, such as copper, aluminum, titanium, etc..
