FIELD: metallurgy.
SUBSTANCE: pipes are made from hot-rolled tube stocks, obtained from hollow ingot billets of electroslag remelting, mechanically processed by boring and turning into tube stocks, which are rolled in a CRT 450 mill into trade pipes with size of 377×8-18 mm.
EFFECT: possibility of reducing the consumption coefficient of metal in the redistribution of the hollow ingot-billet ESR - trade pipe is provided by regulating the methods and modes of billets processing at all stages of production.
