FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy, particularly, to production of thin-wall pipes. Proposed method comprises forming and piercing of solid ingot in container insert by its needle, press ring plate and press ram, as well as quenching, straightening and artificial ageing. Prior to forming with piercing, ingot arranged in said contained is compacted by cupped blank arranged between said ring plate and ram at the needle with aligned ends of the needle and ring plate, and is removed after compaction. Note here that straightening of quenched tube is performed by gaging the tube OD to the rate of deformation of 0.5-2.5.
EFFECT: high strength and precision.
