Zusammenfassung:	A flexible, spiral construction pipe (2) is formed from a narrow plastic ribbon by inter-locking of the toothed edges. - The pipe is located and sent to the required shape. It is then covered with several layers (6) of glass fibre reinforced synthetic resin. When the resin is set, the pipe becomes strong, rigid and corrosion resistant. - Pipe lengths are joined by covering the joint also with several layers of glass fibre re-inforced plastic (7)
