Abstract:
A V-grooved composite insulation is provided with an adhesive coating and a protective jacketing material bonded to the adhesive. The protective jacketing material extends beyond the perimeter of the grooved insulation board and comprises at least one intact release layer at a location in which the protective jacketing is clear of contact with the bottom surface of the insulation member and a pressure sensitive adhesive between the portion of the protective jacketing material and the at least one release layer. The method also comprises preshaping the grooved insulation board around a pipe by bending the grooved insulation board, removing the release layer of the protective jacketing material, thereby exposing the pressure sensitive adhesive and securing the pressure sensitive adhesive to the protective jacketing to thereby surround the pipe in a vapor free manner. Grooved insulation boards with protective jacketing so constructed are also provided.

Abstract:
A protective jacketing-insulation composite structure and method is provided for inhibiting the corrosion of a pipeline. The method includes forming a porous- insulation into an elongated-arcuate-shape, applying a sodium silicate solution layer to the insulation and at least partially within the pores thereof, permitting the sodium silicate solution layer to set to a threshold amount, adhering an outer facing to the sodium silicate solution layer after the permitting step is accomplished, installing the insulation and facing to the outer surface of a pipeline, and sealing any exposed edges or seams that may exist between multiple installed products. A structure such as made from this method can have a release layer and contact adhesive.
