ABSTRACT:
A tubular conduit assembly for confining or conveying a pressurized fluid including a flexible, thin-walled inner tube coaxially disposed within a flexible armor or outer tube. The outer tube is preferably constructed from one or more helically-wound members corresponding with, and engaging, helical corrugations on the inner tube. The inner tube deforms in response to the pressure and/or temperature of the fluid in order to form an internal sealing layer or sleeve-type coating for the outer tube. A shrink fitting assembly is also disclosed, which is adapted for compressingly urging the conduit assembly into an anchored, sealing relationship with a nipple member or other connection device inserted within an open end of the conduit assembly.
