Structural Repair of Steel Piping by In-Situ Sleeving of Nanostructured Materials

The objective of this six month Phase I effort was to establish the technical and economic feasibility of a nanotechnology-based repair concept for the specific application area of in-field gas pipeline repair. Preliminary sleeving experiments performed before the onset of this program have shown that the high strength nanocrystalline metal can successfully “fill” cracks in pipeline steel. However, very few proof-of-concept repair patches have been applied to actually degraded pipeline steel sections and the presumed structural reinforcement effect that is expected to be imparted by these high strength nanometal layers has not been yet verified experimentally and properly quantified. Furthermore, information on how much the in-field pipeline repair process will cost is yet to be determined. This document includes proof-of-concept demonstration of the repair technique and laboratory scale mechanical testing. Preliminary cost modeling is not included.
