Abstract
A wrappable, styrenic thermal insulation product for application to flexible, armored pipe is in the form of an elongate tape of generally rectangular cross-section, optionally being provided with interlocking and/or overlapping portions so as to provide a continuous insulating layer when one or more layers of the tape are wound around the pipe. The interlocking and/or overlapping portions may be of various configurations. The tape is comprised of polystyrene or a styrene-based thermoplastic having high compressive creep resistance, high compressive strength and low thermal conductivity and may be foamed or unfoamed. A flexible, armored pipe incorporates one or more layers of the wrappable, styrenic thermal insulation product between an outer armor layer and an outer polymeric sheath.
