A resin coated section (4) is formed by coating the outer surface (3) of a core pipe (2), which consists of a steel circular pipe, with a resin in such a manner that the resin is in close contact with the outer surface (3). The outline of the transverse cross-section of the resin coated section (4) is a polygon. The entire resin coated section (4) or a part thereof in the longitudinal direction of the core pipe (2) is helically twisted about the axis of the core pipe (2), and the twist is applied only to the resin coated section (4) and not to the core pipe (2).</p> |
