A pipe system includes first and second pipes having first and second ends welded together forming a girth-weld and a corrosion coating covering the girth-weld. In addition, a flexible sheet is provided to cover the girth-weld. The flexible sheet comprises a first structured layer that mechanically couples to the corrosion coating, where the corrosion coating permeates a substantial portion of the first structured layer. The flexible sheet also includes a second layer comprising a polymer layer adhered to the first layer, the second layer protecting the corrosion coating from mechanical or environmental damage. Alternatively, the protective cover comprises a polymer material and includes a port formed therethrough adapted to receive a delivery mechanism that delivers a corrosion coating to the girth-weld.
