Abstract

A hose assembly includes a tubular inner core, a high-temperature thermal insulator disposed about the inner core and in substantially continuous contact therewith, a sealing layer substantially surrounding the thermal insulator, and an outer reinforcing layer. The insulator may be a refractory paper tape braided or helically wrapped about the inner core, and may be multiple layers thick. The sealing layer, which may be a polymeric fluorocarbon tape, substantially surrounds the thermal insulator and protects the thermal insulator from chemical degradation. The outer reinforcing and sealing layer may be integrated. Alternatively, the outer reinforcing layer may be applied about the sealing layer, for example via braiding. A coupling may be attached at one end of the hose assembly to connect the hose assembly to a fluid system.
