Abstract

A method of manufacturing pipes from high-alloy steels and alloys includes heating a billet to the temperature of 1130-1180 °C, application of glassy lubricant, producing a hollow case on vertical hydraulic press, preheating the case, application of glassy lubricant and subsequent extrusion on the tube-shaping press. Extrusion of pipes is performed at the coefficient of drawing 3-18 within the range of temperatures 0.88-0.91 of temperature of grain boundaries flashing. The deformation rate during producing the hollow case is determined from the ratio: where μ - elongation ratio.
