Billet and billet heating, billet perforation, steel tube extension.

High pressure tube rolling, steel tube sizing and reducing, steel tube cooling and finishing, or can be said to be the heating of steel blank perforation, hot stamping, pickling, cold drawing, carbon burning, cutting head, marking packaging finished products a manufacturing method of seamless steel tube, which is characterized by:A rolling stand with multiple rolls is arranged, and a number of mandard seamless tube mills are continuously arranged in different rolling directions to each other. After the seamless steel tube is rolled on such a manufacturing line, the wall thickness of the rolled steel tube in the circumferential direction is measured at multiple points. According to the measurement results,At least the two ends of each shaft of the roll on the final rolling stand of the mandrel seamless tube mill are controlled separately in order to minimize the uneven wall thickness.

General alloy tube & GT;Alloy tube & gt;Alloy tube & gt;High pressure alloy pipe is referred to as seamless steel pipe. It is made of ordinary carbon steel, high quality carbon steel, ordinary low alloy steel and alloy structural steel. It is used for making liquid pipeline or making structure and parts.

The high pressure tube is supplied according to the outer diameter and wall thickness. There are various wall thicknesses under the same outer diameter, and the pressure range of the high pressure tube is larger.Generally, the length of steel pipe is 3-12.5m for hot-rolled pipe and 1.5-9m for cold-drawn (rolled) pipe.
