Stainless steel cross has equal diameter and different diameter

　　Stainless steel cross has equal diameter and different diameter, equal diameter four-way nozzle end are the same size; different diameter stainless steel cross main pipe nozzle size is the same, and branch pipe nozzle size is smaller than the main pipe nozzle size. The stainless steel cross is a kind of pipe fitting used for the branch of pipeline. For the seamless tube manufacturing stainless steel cross, the current commonly used processes are hydraulic bulging and hot pressing.

　　The four way hydraulic bulging is a forming process that expands the branch pipe by axial compensation of metal material.

　　Stainless steel cross hot-pressing forming is to flatten the tube blank larger than four-way diameter to about stainless steel cross diameter and make a hole in the part of drawing branch pipe; the tube blank is heated and put into the forming die, and 3/4" 304 316 Stainless Steel Pipe Fitting Cross is loaded into the drawing branch pipe punching die; under the action of pressure, the tube blank is radially compressed, in the process of radial compression metal toward the branch. The tube flows and forms a branch under the drawing of the die.
