    摘要: An article, for example a pipe, has a first covering such as a polymer layer, and a second covering, such as a repair patch or a repair deposit of melt-on adhesive or a wrap or a sleeve protecting a welded joint between two lengths of such pipe. The second covering may have a functional coating on an underside which is applied on and is at least partially superimposed over the first covering. A cured deposit of thermoset resin is applied at least over the edges of the second covering, for example in the form of a fibrous tape impregnated with a curable resin composition, and bonds to the first and second coverings. The resin deposit provides the second covering with increased stability against displacement laterally of said first covering, for example as a result of soil stress.
