High-pressure alloy tube production process High-pressure alloy tube rolling, Steel Pipe sizing and reduction, steel pipe cooling and finishing or can be said to be a steel embryo heating perforated hot-sand pickling cold-drawn carbon burning cutting head spray packaging finished product A method for producing a seamless steel pipe, comprising: a rolling stand having a plurality of rolls; and a plurality of mandrel mills continuously arranged in mutually different rolling directions, on such a manufacturing line After the seamless steel pipe is rolled, the wall thickness in the circumferential direction of the rolled steel pipe is measured at a plurality of points, and according to the measurement result, at least the rolls on the final rolling stand of the mandrel mill are respectively controlled. The ends of the shaft are positioned to minimize wall thickness unevenness. General alloy tube>alloy tube>alloy tube>high-pressure alloy tube is referred to as seamless steel tube. It is made of ordinary carbon steel, high quality carbon steel, ordinary low alloy steel and alloy structural steel. It is used to make liquid pipeline or make structure and parts. use. The high-pressure pipe is supplied according to the outer diameter and the wall thickness, and has various wall thicknesses under the same outer diameter, and the high-pressure pipe is subjected to a large pressure range. Usually the length of the steel pipe is 3-12.5 m for hot rolled pipes and 1.5-9 m for cold drawn (rolled) pipes.
