Abstract: A fluid pipeline has a first end and a second end. An elongated heat trace element comprised of first and second heat tubes is aligned and coupled to at least a portion of an outer surface of the fluid pipeline. The outer surface of fluid pipeline carries a first insulation material covering a first portion of the outer surface. The outer surface of the fluid pipeline further carries a second insulation material covering a second portion of the outer surface and wherein the second portion of the outer surface is different than the first portion of the outer surface. The first and second insulation materials are configured to cover the outer surface of the fluid pipeline. The fluid pipeline further comprises a third insulation material carried over a second outer surface defined by the cooperation of the first and second insulation materials.
