Thermally resistant convoluted sleeve and method of construction thereof

摘要

A thermally insulative, reflective convoluted sleeve and method of construction thereof is provided. The sleeve includes a resilient inner layer, an outer layer and a resilient intermediate layer sandwiched between the inner and outer layers. The inner layer has an inner surface exposed to an inner cavity of the sleeve and the outer layer has an outer reflective surface exposed to the surrounding environment. The intermediate layer is an impervious sheet material and is sandwiched in abutment with the inner and outer layers. The inner, outer and intermediate layers are convoluted to provide the sleeve with enhanced thermal protection properties and flexibility.

1. A thermally insulative, reflective sleeve for protecting a member against exposure to heat, comprising:
a resilient textile tubular inner layer having an inner surface exposed to a cavity of the sleeve, said inner layer being one of a nonwoven textile material or a woven textile material; a resilient tubular outer layer having an outer reflective surface exposed to the surrounding environment; a resilient tubular intermediate layer constructed of an impervious sheet material sandwiched between said inner and outer layers; and said inner, outer and intermediate layers being resiliently, radially compressible and expandable and convoluted to provide the sleeve with an enhanced flexibility to be routed over meandering paths.
