Abstract:
Methods are provided for lining and wrapping both interior and exterior surfaces of tubular structures with materials that protect the underlying structures from adverse environmental conditions, provide a thermal control coating and prevent exchanging moisture with the surrounding environments. The methods use adhesives to securely position the lining or wrapping material inside or around the exterior of the tubular structure. The adhesives prevent the formation of discontinuities in the protective layer provided by the lining or wrapping material by holding the protective materials in place during the fabrication process. The wrapping materials are sealed by an ultrasonically welded seam to prevent environmental attack through the seam to the underlying tubular structure.
