FIELD: metallurgy; hardening of oil grade pipes made from carbon steel and low-alloy steel (Nb, V, Mo and Cr) directly in the course of hot deformation.
SUBSTANCE: proposed method includes preliminary deformation of pipes, holding them in air, heating to 800-870 C for final deformation and accelerated adjustable cooling to 720-760 C performed during repeated hot deformation in compressed-to-solid state at average rate of cooling of 40-60 C/s in center of deformation and 20-30 C/s during inter-deformation intervals.
EFFECT: possibility of obtaining pipes of required geometric parameters in ovality and linearity at enhanced strength, ductility and heat resistance of steel.
