FIELD: metallurgy.
SUBSTANCE: pipes are made from centrifugally cast tubular workpieces of regulated size, which are bored and ground into hollow machined workpieces, heated and rolled on a Pilger mill into rerolled hot-rolled pipes, and then rolled on KhPT mills in trade pipes.
EFFECT: reduction in the products cost is ensured by the choice of the original workpiece and its regulatory processing mides in all industries.
