Abstract:
A method of heat insulating a pipe comprising the steps of:(a) preparing a pumpable heat insulation composition comprised of a liquid epoxy resin comprising a condensation product of epichlorohydrin and bisphenol A, a diluent selected from the group consisting of aromatic hydrocarbons and epoxide containing liquids, an insulating material comprised of hollow inorganic spheres present in an amount in the range of from about 50% to about 100% by weight of said liquid epoxy resin in said composition and an epoxy resin hardening agent which is at least one member selected from the group consisting of aliphatic amines, aromatic amines, amide amines, amido amines, imadazoles and carboxylic acid anhydrides present in an amount in the range of from about 10% to about 35% by weight of said liquid epoxy resin said composition;(b) placing said insulation composition adjacent to surfaces of said pipe; and(c) allowing said insulation composition to harden.
