What Are The Forming Processes For Stainless Steel Pipe Fittings?

For stainless steel pipe fittings, a reasonable forming process is very important during the production process. So what are the forming processes for stainless steel pipe fittings?

Stainless Steel Weld Tee Hydraulic bulging is a forming process that bulges the branch pipe through axial compensation of metal materials. In this process, a special hydraulic press is used to inject liquid into the tube billet with the same diameter as the tee, and the tube billet is squeezed by two horizontal side cylinders of the hydraulic press, so that the volume of the tube billet becomes smaller after extrusion, and the pressure of the liquid in the tube billet increases as the volume of the tube billet becomes smaller. When the pressure required for the expansion of the tee branch pipe is reached, the metal material flows along the inner cavity of the mold under the dual action of the side cylinder and the liquid pressure in the tube billet, causing the branch pipe to expand.

The hot pressing forming of stainless steel tee pipe fittings is to flatten the tube billet larger than the tee diameter to the size of the tee diameter, and open a hole at the part where the branch pipe is stretched. After the tube billet is heated, it is placed in the forming mold, and a mold for stretching the branch pipe is provided in the tube billet; under the action of pressure, the tube billet is radially compressed, and during the radial compression process, the metal flows to the branch pipe, and the branch pipe is formed under the stretching of the mold. The whole process is formed by radial compression of the tube billet and stretching of the branch pipe. Unlike hydraulic bulging tees, the metal of hot-pressed tee branches is compensated by the radial movement of the tube blank, so it is also called radial compensation process.

The above is an introduction to the forming process of stainless steel pipe fittings.
