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. ## Claims ### Claim 1 A method for inhibiting pipe corrosion, the method comprising the steps of: (a) forming a porous insulation into an elongated-arcuate-shape, (b) applying a copolymer-sodium silicate solution layer to at least the exterior surface of the insulation and at least partially within the pores of the insulation, (c) permitting the copolymer-sodium silicate solution layer to set to a threshold amount, (d) adhering an outer protective jacketing to the copolymer-sodium silicate solution layer, after the permitting step is accomplished, (e) installing the product made in steps (a)-(d) onto the exterior surface of a pipe or piece of equipment, and (f) sealing any exposed edges or seams between adjacent products installed in step (e) or between overlapping sheets of said protective jacketing. ### Claim 2 (depends on 1) The method of claim 1, wherein the insulation is comprised of calcium silicate, mineral fiber, rock mineral wool, slag mineral wool, perlite, fiber glass, or a combination thereof. ### Claim 3 (depends on 1) The method of claim 1, wherein the adhering step comprises adhering a continuous outer protective jacketing to the copolymer-sodium silicate solution layer without any intervening layer. ### Claim 4 (depends on 1) The method of claim 1, wherein the forming step comprises forming first and second elongated arcuate-shaped insulation members which are combinable so as to define a tube. ### Claim 5 (depends on 3) The method of claim 3, wherein the first and second elongated insulation members are at least partially interconnected by an outer protective jacketing. ### Claim 6 (depends on 3) The method of claim 3, including the additional step of bonding the first and second elongated insulation members to one another along an interface. ### Claim 7 (depends on 6) The method of claim 6, wherein the first and second elongated insulation members have respective first and second edges, and wherein the bonding step bonds the respective first and second edges to one another. ### Claim 8 (depends on 6) The method of claim 6, wherein the bonding step comprises bonding the respective first and second edges with a glue comprised of a copolymer-sodium silicate solution. ### Claim 9 (depends on 1) The method of claim 1, wherein the applying step comprises brushing the copolymer-sodium silicate solution onto the insulation. ### Claim 10 (depends on 1) The method of claim 1, wherein the applying step comprises spraying the copolymer-sodium silicate solution onto the insulation at a low pressure. ### Claim 11 (depends on 5) The method of claim 5, wherein the protective jacketing comprises a multilayer laminate of foils, plastic film, and optionally fiberglass cloth. ### Claim 12 A method for inhibiting pipe corrosion, the method comprising the steps of: (a) disposing a porous-insulation around the pipe; (b) applying a copolymer-sodium silicate solution layer to the insulation and at least partially within the pores of the insulation, as a coating; and (c) adhering an outer protective jacketing to the copolymer-sodium silicate solution layer while the applied sodium silicate solution layer remains tacky. ### Claim 13 (depends on 12) The method of claim 12, wherein the disposing step comprises surrounding the pipe with first and second elongated arcuate-shaped insulation members. ### Claim 14 (canceled) ### Claim 15 (canceled) ### Claim 16 (canceled) ### Claim 17 (canceled) ### Claim 18 (canceled) ### Claim 19 (canceled) ### Claim 20 (canceled) ### Claim 21 (canceled)
