ABSTRACT:
A pipeline casing insulator to support a coated pipe within a tubular, metallic casing. The pipeline casing insulator comprises a flexible belt formed of a material that is capable of bonding to an organic resin. A plurality of parallel bar-like runners are formed from an insulative and non-abrasive polymer concrete that is cast onto an outer facing surface of the belt. The belt is preferably a strip of an organic non-woven material. The polymer concrete is preferably a mixture of a thermosetting polymer resin, such as epoxy, polyester or polyurethane, and an aggregate. The aggregate preferably comprises a mixture of substantially incompressible coarse particulate material, such as sand or gravel, and fine filler material, such as calcium carbonate, silica flour, or kaolin. The inner facing surface of the belt preferably has a mastic coating covered by a release paper that can be removed, to allow attachment of the belt to the outer surface of the pipe by circumferentially wrapping the belt around the pipe.
