The present invention is easy to processing such as cutting, strength is strong, lightweight, to provide a resin pipe that can be low-cost. The invention relates to a resin pipe 16 of hollow extruded. A regular hexagonal columnar cylindrical body 20 consisting of six side walls 18 (1) to 18 (6), arranged radially in the direction from the position of the center axis of the cylindrical body 20 to the inner wall surface of the tubular body 20 6 One of the reinforcing walls 22 (1) and a to 22 (6). Reinforcing walls 22 (1) to 22 (6), the end of the inside are continuous with each other at the position of the central axis, the outer end portions are continuous respectively to the inner wall surface of the cylindrical body 20. .BACKGROUND【課題】切断等の加工が容易で、強度が強く、軽量化、低コスト化が可能な樹脂パイプを提供する。【解決手段】押出成形された中空の樹脂パイプ16である。6つの側壁18(1)~18(6)で成る正六角柱状の筒状本体20と、筒状本体20の中心軸の位置から筒状本体20の内壁面に向かって放射状に設けられた6つの補強壁22(1)~22(6)とを有する。補強壁22(1)~22(6)は、その内側の端部が前記中心軸の位置で互いに連続し、外側の端部が筒状本体20の内壁面にそれぞれ連続している。【選択図】図1
