Sistema aislante hibrido que comprende una tuberia que tiene un interior hueco configurado para llevar de manera fluida un material y al menos un elemento termico dispuesto en una superficie exterior de la tuberia, una primera capa aislante que comprende una primera y segunda porcion aislante, una segunda capa aislante que abarca la primera capa aislante y se configura para extenderse a lo largo de la superficie exterior de la tuberia.

摘要

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.
