Document Type and Number:
WIPO Patent Application WO/2017/126597
Kind Code:
A1
Abstract:
Provided are: a coiling structure for resin pipe, which can be loaded and transported on a vehicle in a coiled state while suppressing permanent deformation; a method for producing a coiling structure; a method for laying down a resin pipe; and a resin pipe. The present invention pertains to a coiling structure which is for a resin pipe, which is composed of a material having a yield stress (MPa) / elastic modulus (MPa) ratio of 0.010-0.050, and which has an outer diameter of 50.0-130.0 mm and a thickness of 2.0-15.0 mm, wherein the following relations are satisfied: 3500.0 mm ≥ the maximum width (mm) of the outer periphery of the coiling structure; and the minimum width (mm) of the inner periphery of the coiling structure ≥ 0.62 × outer diameter of resin pipe ÷ (yield stress / elastic modulus).
