Stainless steel socket welding cross four-way high pressure pipe fittings 304 316L

Stainless steel socket cross are divided into equal diameters and different diameters. The ends of the equal diameter spools have the same size; the main diameters of the reduced diameter spools are the same, and the size of the branch pipe is smaller than the size of the main pipe. Stainless steel cross is a kind of pipe fitting used at the branch of pipeline. For the use of seamless tubes to manufacture four-way, currently commonly used processes are hydraulic expansion and hot press forming. A. Hydraulic bulging Four-way hydraulic bulging is a forming process that expands the branch pipe through the axial compensation of the metal material. The process is to use a special hydraulic machine to inject liquid into the tube blank equal to the diameter of the four-way, and squeeze the tube blank through the centering movement of the two horizontal side cylinders of the hydraulic machine. As the volume of the tube blank becomes smaller, the pressure rises. When the pressure required for the expansion of the four-way branch tube is reached, the metal material flows along the cavity of the mold under the double action of the liquid pressure in the side cylinder and the tube tube to expand the branch tube. The hydraulic bulging process of the four-way can be formed at one time, and the production efficiency is higher; the wall thickness of the main pipe and shoulder of the four-way is increased. Because of the large tonnage of the equipment required for the hydraulic bulging process of the seamless four-way, it is currently mainly used in the manufacture of standard wall thickness four-way less than DN400 in China. The applicable forming materials are low carbon steel, low alloy steel and stainless steel with relatively low cold work hardening tendency, including some non-ferrous metal materials such as copper, aluminum and titanium. b. Hot press forming Four-way hot press forming is to flatten the tube blank larger than the diameter of the four-way tube to the size of the four-way diameter, and to make a hole in the stretched branch pipe; the tube blank is heated and put into the forming die , And put the drawing die of the drawing branch pipe into the tube blank; under the action of pressure, the tube blank is compressed radially. During the process of radial compression, the metal flows toward the branch tube and forms the branch tube under the drawing of the die. The whole process is formed by the radial compression of the tube blank and the stretching process of the branch pipe. Different from the hydraulic bulge spool, the metal of the hot-press spool branch is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.
