硬化性樹脂を含浸して成る管状樹脂吸着材を流体圧によって管状に押し広げた状態で該管状樹脂吸着材に含浸された硬化性樹脂を硬化させることによって、管路全長よりも長さが短く、管路内径よりも小さな外径を有するプラスチックパイプを得ることを特徴とするプラスチックパイプの製造方法。 By curing the curable resin impregnated in the tubular resin adsorbent in a state where the tubular resin adsorbent impregnated with the curable resin is expanded in a tubular shape by fluid pressure, the length is shorter than the entire length of the pipe line. A method for producing a plastic pipe, characterized in that a plastic pipe having an outer diameter smaller than the inner diameter of the pipe is obtained. 前記管状樹脂吸着材を管路の入口部に導入し、該管状樹脂吸着材の内部にインライナーを流体圧によって反転挿入し、該インライナーの内部に流体圧を作用させて管状樹脂吸着材を管状に押し広げることを特徴とする請求項１記載のプラスチックパイプの製造方法。 The tubular resin adsorbent is introduced into an inlet portion of a pipe line, an inliner is inverted and inserted into the tubular resin adsorbent by fluid pressure, and the fluid pressure is applied to the inside of the inliner so that the tubular resin adsorbent is 2. The method for producing a plastic pipe according to claim 1, wherein the plastic pipe is expanded in a tubular shape.
