Stainless steel cross refers to a water pipe joint made of stainless steel, which is a pipe fitting used at the branch of the pipe.
Stainless steel cross can be divided into equal diameter and reducing diameter, and the nozzle ends of equal diameter cross are of the same size; The size of the main pipe of the reducing cross is the same, while the size of the branch pipe is smaller than that of the main pipe.
Standard: DIN,ANSI,ASTM,JIS
Material: carbon steel
Size: dn10mm-1828mm
Thickness: 2mm-45mm
Surface treatment: antirust black paint, Epoxy coating

Stainless steel cross adopts the forming process of hydraulic bulging, which is a forming process of expanding the branch pipe through the axial compensation of metal materials.
The process is to use a hydraulic press to inject liquid into the tube blank with the same diameter as the cross, and squeeze the tube blank through the synchronous centering movement of the two horizontal side cylinders of the hydraulic press.
After being extruded, the volume of the tube blank becomes smaller, and the liquid in the tube blank increases with the volume of the tube blank. When the required pressure is reached, the metal material flows along the inner cavity of the die and expands out of the branch pipe.
Stainless steel cross is widely used in major power plants, chemical industry, light industry, metallurgy, urban construction, shipbuilding, natural gas engineering, food manufacturing, papermaking, medicine and other industries at home and abroad.
