FIELD: metallurgy.
SUBSTANCE: invention relates to pipe rolling production for manufacturing the coupling pipes of 132.1×18×10600-10800 mm size from corrosion-resistant alloy of KHN30MDB grade used for gas and gas condensate extraction inhydrogen sulfide-containing media. The casting of centrifugally cast billets of 470×115×2700±50 mm size is carried out from the alloy of KHN30MDB grade, their boring and turning, heating, rolling on the conical drawbars, cooling, cutting, boring and subsequent rolling on cold-pilgering mill with regulated modes of treatment and rolling.
EFFECT: reduction of metal consumption.
