High temperature fire sleeve

摘要

A flexible hose (100) for conveying fluids and suitable for high temperature environments, the hose (100) comprising a core tube (110), a thermal insulating layer (130) surrounding the core tube (110), a metal layer surrounding the thermal insulating layer (130), and a vented jacket (150) surrounding the cover layer (140). The thermal insulating layer (130) may be a fibrous material such as a silica fibre. The metal layer may also be a chemical resistant layer and be thermally stable up to at least about 288°C (550°F). The vented jacket (150) may be a wire braid having interstices therein and formed from a corrosion resistant material.
