Abstract (en)
[origin: WO0006933A2] A tubular system made up of a tubular, a liner in the tubular, and longitudinally oriented members, which may be disposed within channels in the liner. The members advantageously may be used for pulling a liner into a host tubular, and/or maintaining the structural strength of the liner. The members are continuous along the length of the plastic-lined tubular, and if applicable, through intermediary joints. The channels may be in the inner and/or outer surfaces of the liner. The members may be usable for carrying electrical current or signals, fiberoptic signals, or data communications; for heating the liner; and/or for detecting faults in the liner and/or the host tubular.
[origin: WO0006933A2] A tubular system made up of a tubular (10), a liner (12) in the tubular (10), and longitudinally oriented members (15, 16, and 17), which may be disposed within the channels in the liner. The members advantageously may be used for pulling a liner into a host tubular, and/or maintaining the structural strength of the liner (12). The members are continuous along the length of the plastic-lined tubular (10), and if applicable, through intermediary joints. The channels may be in the inner and/or outer surfaces of the liner (12). The members may be usable for carrying electrical current or signals, fiberoptic signals, or data communications; for heating the liner; and/or for detecting faults in the liner and/or the host tubular (10).
