FIELD: plastic metal working. SUBSTANCE: initial solid blank is heated to the forging temperature. The central hole is formed by loosening and opening of the blank core subjected simultaneously to the effect of two pairs of strikers and arbor with piercing end piece. During this process the blank is rotated with the angle of turning between strikes equal to 13-15 deg and is fed in the direction of the strikers at a preset speed. Then the pipe is sized beginning from the same heating and on the same arbor without the piercing end piece. Device for realizing the method has arbor and two pairs of strikers mounted with the shift of their working surfaces along the axis of forging. Each pair of the strikers is adjusted to the preset size of compression and to ensuring the total degree of compression from 5 to 25 % . The arbor is provided with quick-detachable piercing end piece. EFFECT: extending operating capabilities. 3 cl, 7 dwg
