METHOD OF PRODUCING COLD-DEFORMED COUPLING PIPES OF 132,1 × 18 × 11.750-12.350 mm SIZE FROM CORROSION-RESISTANT ALLOY OF "ХН30МДБ" GRADE Russian patent published in 2017 - IPC B21B21/00

Abstract RU 2614477 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to the pipe rollingfor manufacturing the coupling pipes for tubing used for production of gas and gas condensate extraction in hydrogen sulfide-containing media. Hollow centrifugal cats workpieces are used, which are bored and rolled on the Pilger mill and then KhPT mills to the size of 132.1×18×11.750-12.350 mm.

EFFECT: reduction in the metal consumption in the manufacture of cold-deformed pipes provided by the regulation of workpiece processing modes at all stages of production.
