High pressure fluid conduit assembly

A tubular conduit assembly for conveying a pressurized fluid, comprising:

• plastic inner tube for conveying said pressurized fluid;
• a flexible metal outer tube disposed coaxially around said inner tube, said outer tube comprised of at least two alternating facing, U-shaped metal strips which are helically wound together and slidably engaged, a predetermined radial separation between the exterior diameter of said inner tube and the interior diameter of said outer tube, and at least one portion of said outer tube is deformed by crimping for decreasing the flexibility of said outer tube and retaining the shape of said portion of said conduit assembly.

A disparate piping system for conveying a pressurized fluid, comprising:

• at least two rigid metal tubes each having a predetermined shape;
• and
• at least one conduit assembly connected between said rigid metal tubes, said conduit assembly including a plastic inner tube for conveying said pressurized fluid, and a flexible metal outer tube disposed coaxially around and containing said inner tube, said outer tube being comprised of two alternately facing metal strips which are helically wound together and slidably engaged, at least one portion of said outer tube is deformed for decreasing the flexibility of said outer tube and retaining the shape of said portion of said conduit assembly, and a predetermined radial separation between the exterior diameter of said inner tube and the interior diameter of said outer tube.

• at least two rigid metal tubes each having a predetermined shape;
• at least one conduit assembly connected between said rigid metal tubes, said conduit assembly including a plastic inner tube for conveying said pressurized fluid and a flexible metal outer tube disposed coaxially around said inner tube, said outer tube being constructed from a plurality of interlocking, generally channel-shaped members, a predetermined rate of separation between the exterior diameter of said inner tube and the interior diameter of said outer tube, a connector member secured at each end of said conduit assembly, each of said connector members having an elongated tubular portion inserted into said inner tube at one end of said conduit assembly, said tubular portion including an enlargement at the end of said connector member, said outer tube of said conduit assembly being deformed along said tubular portion of said connector member between the end of said outer tube and said enlargement such that the interior diameter of said outer tube is reduced, and
• a reinforcing sleeve element is interposed between said inner tube and said outer tube along said tubular portion of said connector member.
