  • Heat shrinkable wraparound articles for covering elongate objects
    Patent number: 5397615
    Abstract: A wraparound heat shrinkable sheet for covering pipes or cables is positioned therearound so its longitudinal edges overlap. A first patch is then positioned over the lapped edges, and a second patch, which is wider than the first patch, positioned over the first patch and secured to the underlying wrapped sheet. Heat is then applied, preferably by hot mastic. The heat acts to shrink the sheet which tensions the second patch, thereby directing a radial force downward onto the first patch.

  • Elongated substrate with polymer layer covering
    Patent number: 4997685
    Abstract: The invention relates to a method for applying a protective coating to a substrate, such as metallic pipe, which comprises applying onto the substrate a liquid curable polymeric composition capable of curing to a substantial extent within about 24 hours at less than about 80.degree. C., then applying one or more polymeric layers, the innermost of which is capable of interacting with said curable composition, and permitting the composition to cure. In certain embodiments the polymeric layer is applied as a polymeric article, in other embodiments a multiple layer polymeric covering is applied over the curable composition.
