An improved device (11) and process for creating a lining in a bore, transfers strip wrapped in overlapping spiral fashion about a mandrel (4) to the bore wall such that the edge-to-edge relation of the spirally-wrapped strip (21) is maintained from the mandrel (4) to the bore wall. Adhesive is applied to the strip surface during wrapping thereof on the mandrel (4). The invention provides a new bore with a thin, strong, corrosion resistant lining over a preselected portion of its length that is substantially pressure tight internally and externally and leak proof thus permitting substantial reuse of the lined bore. |
