Pipe cross is a kind of pipe fittings used for pipe branch. Pipe cross is divided into equal diameter and different diameter. The nozzles of equal cross are the same size; the nozzles of reducing cross are the same size, while the nozzles of branch are smaller than the nozzles. For butt weld cross cross manufacturing, there are two commonly used processes: hydraulic bulging and hot pressing. Hydraulic bulging is a kind of forming of expanding branch pipe by axial compensation of metal material. The process is to use a special hydraulic press to inject liquid into the billet with the same diameter of the cross pipe. The billet is extruded synchronously through the two horizontal cylinders of the hydraulic press. The volume of the billet decreases after extrusion, and the liquid in the billet increases with the volume of the billet. When the pressure required for the expansion of the cross branch pipe is reached, gold will be extruded. The material expands the branch pipe by flowing along the inner cavity of the die under the double action of liquid in the side cylinder and tube blank. Cross hydraulic bulging process can be formed at one time, and the production efficiency is high. Cross main pipe and shoulder wall thickness are increased. Because the hydraulic bulging process of seamless cross needs a large tonnage of equipment, it is mainly used in the manufacture of standard wall thickness cross less than dn400 in china at present. The pipe cross is manufactured by hydraulic forming process.
when quoting a price for pipe cross connection, it is necessary to accurately inform the pipeline pressure used, or directly inform the elbow wall thickness, so as to report the precise price. There are sch10s sch20s and other different pressure grades which conventionally express the elbow wall thickness, representing different thickness. You can refer to the pressure grade wall thickness table.
