FIELD: metallurgy.
SUBSTANCE: method involves casting hollow ingots by electroslag remelting, their refacing into ingot workpieces, ingot workpieces heating in the reheating furnace, lubricating, supply of hollow ingot workpieces on the front side of the Pilger mill, their rolling at the Pilger mill, straightening, pipes cutting into two pipe of equal length, mechanical processing-boring and turning into the tube stock workpieces and rolling of mechanicalyy procedded tube stock workpieces on KhPT 450 mill into trade pipes.
EFFECT: reduced expensive metal consumption, reduced roughness of outer and inner pipes surfaces, improved productivity and increased pipes lengths, reduced cost provided by regulation of workpieces processing modes at all stages of production.
