CORRUGATED PIPE AND MANUFACTURING METHOD THEREFOR

To provide a resin-based corrugated pipe excellent in pressure resistance and flexibility, and a manufacturing method for the resin-based corrugated pipe capable of molding a plurality of uneven shapes with a single cycle.SOLUTION: A resin-based corrugated pipe 1 comprises a tubular member 10, wherein an annular ridge 11 that is convex outward in a radial direction of the tubular member 10 and an annular valley 12 that is concave outward in the radial direction of the tubular member 10 are alternately formed in an axial direction to form a bellows shape, wherein a ratio (D1/t1) of an outer diameter D1 of the tubular member 10 at the peak of the ridge 11 to a radial thickness t1 of the tubular member 10 at the peak of the ridge 11 is 17 or less.SELECTED DRAWING: Figure 1 【課題】耐圧性および可撓性に優れる樹脂製のコルゲート管を提供する。複数の凹凸形状を１回のサイクルで成型することができる樹脂製のコルゲート管の製造方法を提供する。【解決手段】管状部材１０からなり、管状部材１０の径方向外側へ凸となる環状の山部１１と、管状部材１０の径方向外側が凹となる環状の谷部１２とが軸方向に交互に形成されて蛇腹状とされた樹脂製のコルゲート管１であって、山部１１の頂点における管状部材１０の径方向の厚みｔ１に対する山部１１の頂点における管状部材１０の外径Ｄ１の比（Ｄ１／ｔ１）が１７以下であるコルゲート管１。【選択図】図１
