US Patent:

56853440, Nov 11, 1997

Filed:

Nov 2, 1995

Appl. No.:

8/556751

Inventors:

Ralph A. Iorio - Bloomfield Hills MI
Glen A. Gibbs - Warren MI

Assignee:

ITT Corporation - New York NY

International Classification:

F16L 5300

US Classification:

138140

Abstract:

A composite small-diameter tubing resistant to interaction with materials conveyed therethrough such as liquids containing alcohols or corrosive agents which includes a cylindrical outer metal conduit having a hollow central shaft extending longitudinally therethrough defined by an interior wall; and a continuous non-reactive interior tube surrounded by and positioned within the cylindrical metal conduit. The tubing can be manufactured by a process which includes the steps of a) positioning a length of non-reactive tubing having a predetermined outer diameter within an inner diameter of metal tubing of essentially corresponding length, the metal tube having an unsealed side seam, wherein the inner diameter is greater than the outer diameter of the non-reactive tubing; and b) sealing and reducing the metal tubing to an outer diameter essentially equal to the predetermined outer diameter of the interior tubing. The non-reactive interior tube may be made of a suitable polymeric material.

Abstract:

A multi-layer tube having a metal tube having an outer surface and a zinc layer bonded to the metal tube outer surface. The zinc layer being selected from the group consisting of zinc plating, zinc nickel alloys, zinc cobalt alloys, zinc aluminum alloys, and mixtures thereof. A surface treatment layer is bonded to the zinc layer, wherein the surface treatment layer is selected from the group consisting of a zinc/aluminum/rare earth alloy, phosphate, chromate and mixtures thereof. A first polymeric layer is bonded to the surface treatment layer, wherein the first polymeric layer is selected from the group consisting of a thermoplastic elastomer, an ionomer, a nylon, a fluoropolymer, and mixtures thereof. A second polymeric layer is bonded to the first polymeric layer, wherein the second polymeric layer is selected from the group consisting of a nylon, a thermoplastic elastomer, a fluoropolymer, and mixtures thereof. The tube also has a continuous interior layer made of non-reactive material which is preferably made of a polymeric material which is substantially non-reactive in the presence of short chain alcohols.

Abstract:

A multi-layer tube comprises a metal tube having an outer surface and a zinc layer bonded to the metal tube outer surface, wherein the zinc layer is selected from the group consisting of zinc plating, zinc nickel alloys, zinc cobalt alloys, zinc aluminum alloys, and mixtures thereof. A surface treatment layer is bonded to the zinc layer, wherein the surface treatment layer is selected from the group consisting of a zinc/aluminum/rare earth alloy, phosphate, chromate and mixtures thereof. A first polymeric layer is bonded to the surface treatment layer, wherein the first polymeric layer is selected from the group consisting of a thermoplastic elastomer, an ionomer, a nylon, a fluoropolymer, and mixtures thereof. A second polymeric layer is bonded to the first polymeric layer, wherein the second polymeric layer is selected from the group consisting of a nylon, a thermoplastic elastomer, a fluoropolymer, and mixtures thereof. A process for manufacturing a multi-layer tubing for conveying fluids in a vehicle system comprises the step of extruding multiple layers of a melt-processible thermoplastic to a pretreated metal tube having an external surface with at least a zinc based coating and a sealant coating on top of the zinc based coating.
