The Main Production Process of High-pressure Pipe

The Main Production Process of High-pressure Pipe The main production process of high-pressure pipe: billet heating, perforated tube, pipe extension. High-pressure pipe rolling, pipe sizing and reducing, finishing and cooling pipe or the manufacturing method can be said Billet heating perforation heat tie pickling cold drawn carbon burning cutting head spray subscript finished packing one kind of seamless steel pipe characterized in that: setting a plurality of rolling stands having rolls to the rolling direction of mutually different configuration of multiple continuous mandrel mill, in such a seamless steel pipe manufacturing line for rolling after measuring pipe circumferential direction after rolling on the multi-point, according to the measurement results, at least control the positions of the respective ends of the shaft mandrel mill the final rolling mill roll base, so uneven wall thickness to a minimum. Usually alloy pipe> alloy tube> alloy tube> high alloy seamless steel pipe referred to by ordinary carbon steel, high carbon steel, alloy steel and common low-alloy structural steel for the production of liquid transportation pipeline or production structure, parts use. High-pressure pipe diameter and wall thickness available, there are a variety of wall thickness in the same outer diameter, the larger high-pressure pipe pressure range. Typically the length of steel, hot-rolled tube 3-12.5m, cold drawn (rolled) pipe is 1.5-9m. Post time: Apr-18-2023
