FIELD: plastic working of metals. SUBSTANCE: method involves subjecting ridge forming screen to deformation by longitudinal drawing; convoluting pipe to obtain coiled corrugated hose with outer screen made from profiled tape. Apparatus has conductor provided with at least three forming rollers positioned at both sides of ridge for displacement one relative to the other transverse to tape feeding direction. EFFECT: increased efficiency, simplified method and improved quality of pipes. 3 cl, 8 dwg
