FIELD: metallurgy.
SUBSTANCE: pipes are made of stock hot-rolled pipes, obtained by machining of hot-rolled pipes rolled on TPU 8-16" with pilger mills from hollow centrifugal cast billets.
EFFECT: ability to produce high-quality pipes from centrifugally cast billets without the outer surface turning and reducing the cost of tubing of this assortment is provided by regulating the methods and modes of billets processing at all pipe production stages.
