Butt Weld Carbon/Stainless Steel Fittings Four Way

Four-way hydraulic expansion is a forming process in which branch pipes are expanded by axial compensation of metal materials. The process is to use a special hydraulic press, will be equal to the diameter of the tube billet injection liquid

Body, through the two horizontal side cylinders of the hydraulic press synchronous movement extrusion tube billet, the volume of the tube billet becomes smaller, the liquid in the tube billet with the volume of the tube billet decreases and the pressure increases, when reaching the pressure required by the expansion of the four-way branch pipe, the metal material in the side cylinder and the liquid pressure in the tube billet flow along the mold cavity and expand the branch pipe. The hydraulic bulging process of four ways can be formed at one time, and the production efficiency is higher. The main and shoulder wall thickness of the four channels have increased. Due to the large tonnage of equipment required by the hydraulic bulging process of seamless four-way, it is mainly used for the manufacture of four-way with standard wall thickness less than DN400 in China. Its suitable forming materials for cold work hardening tendency is relatively low low carbon steel, low alloy steel, stainless steel, including some non-ferrous materials, such as copper, aluminum, titanium and so on.
