ABSTRACT:
A tubular conduit assembly for conveying a pressurized fluid is described which includes a plastic inner tube for conveying the pressurized fluid, and a flexible metal outer tube disposed coaxially around the inner tube. The outer tube is constructed from a plurality of interlocking, generally channel-shaped members. In one form of the present invention, the outer tube is comprised of two alternately facing, U-shaped metal strips which are helically wound together and slidably engaged. A predetermined radial separation is provided between the exterior diameter of the inner tube and the interior diameter of the outer tube. This predetermined separation permits a limited amount of expansion for the inner tube while resisting a blowout at normally high pressures and temperatures. While the conduit assembly is initially flexible to facilitate routing, one or more portions of the conduit assembly may be made less flexible, semi-rigid or rigid in order to retain a desired shape of the conduit assembly. According to one technique the outer tube is deformed so that the metal strips of the outer tube are no longer slidably engaged. Additionally, a flexibility reducing material may be injected into the radial separation between the inner and outer tubes, or the flexibility reducing material may be applied to the outer tube along the appropriate portion(s) of the conduit assembly. The conduit assembly may be connected between two rigid metal tubes using snap-type quick connectors to form a disparate piping system.
