A composite fuel and vapor tube having increased heat resistance with a composite wall having a relatively thin nylon liner, a metal strip about the liner and having a longitudinal seam, the tube being encased within a polyethylene jacket. The line thus formed has increased resistance to heat, abrasion and various fuels, is bendable and is capable of maintaining its shape after bending or forming operations.

A bendable tubular article for transport of fuels such as gasoline, diesel fuel, methanol, ethanol, sour gas and the like comprising: (a) a flexible tubular liner made of petroleum resistant material; and (b) a bendable metal strip surrounding the liner throughout its length in a sufficient thicknes
A bendable tubular article for transport of fuels such as gasoline, diesel fuel, methanol, ethanol, sour gas and the like comprising: (a) a flexible tubular liner made of petroleum resistant material; and (b) a bendable metal strip surrounding the liner throughout its length in a sufficient thickness to form a bendable tubular composite having an unsupported self-sustaining shape when bent and sufficient heat dissipation capabilities to rapidly dissipate heat axially along the strip to prevent localized overheating of the article due to exposure to heat or sparks; wherein the self sustaining characteristic of said composite is greater than the flexibility of said liner so that the article retains its shape after bending. A bendable tubular article for transport of fuels such as gasoline, diesel fuel, methanol, ethanol, sour gas and the like comprising: (a) a liner made of petroleum resistant material of a thickness sufficient to contain petroleum fuel but less than about 0.5 mm; (b) an aluminum strip surrounding said liner throughout its length, having a thickness of between about 0.2 and 0.4 mm and having two longitudinal margins which meet to form a seam, said strip providing a fuel vapor permeation barrier and a thermal barrier which rapidly dissipates heat axially therealong; and (c) an adhesive layer on at least the outer surface of said strip to adhere said margins forming the seam so as to form a bendable tubular composite having an unsupported, non-kinking, self-sustaining shape when bent. A bendable tubular article for transport of fuels such as gasoline, diesel fuel, methanol, ethanol, sour gas and the like comprising: (a) a plastic liner made of petroleum resistant material; (b) a bendable metal strip surrounding said liner throughout its length such that said liner is movably disposed therein and said metal strip being of a thickness sufficient to reduce moisture vapor transmission through the article and to form a bendable tubular composite having an unsupported self-sustaining shape when bent having sufficient heat dissipation capabilities to rapidly transmit and dissipate heat axially therealong to reduce and minimize the size and intensity of hot spots upon said article caused by weld spatter, sparks and the like; (c) an adhesive layer on the outer surface of said metal strip; and (d) a plastic jacket encasing said metal strip and adhered thereto by said adhesive layer such that said article can be bent to a desired shape and the metal strip will dominate to hold the article in the desired shape. A bendable tubular article for transport of fuels such as gasoline, diesel fuel, methanol, ethanol, sour gas and the like comprising: (a) a liner made of petroleum resistant material of a sufficient thickness necessary to contain petroleum fuel but less than about 0.5 mm; (b) an aluminum strip surrounding said liner throughout its length having a thickness between about 0.2 and 0.4 mm and having two longitudinal margins which meet to form a longitudinal seam, said strip providing a fuel vapor permeation barrier and a thermal barrier which rapidly dissipates heat axially therealong; (c) an adhesive layer on the outer surface of said strip to adhere said margins forming the longitudinal seam; and (d) a jacket encasing said aluminum strip and adhered thereto by said adhesive layer; the thickness of the aluminum layer in said article being sufficient to form a bendable tubular composite having an unsupported, non-kinking self-sustaining shape when bent. A bendable tubular article for transport of fuels such as gasoline, diesel fuel, methanol, ethanol, sour gas and the like comprising: (a) a cylindrical liner made of nylon and having an axial passage therethrough; (b) an aluminum strip having a thickness between about 0.2 and 0.4 mm and having two longitudinal margins which are wrapped to form a longitudinal lap seam at he overlap of said margins and encases said liner, said strip providing a fuel vapor permeation barrier and a thermal barrier which rapidly dissipates heat axially therealong; (c) an adhesive layer of a copolymer of ethylene and a monomer having a reactive carboxyl group coating both the inside surface and the outside surface of said aluminum strip and bonding the inner surface of one longitudinal margin of said aluminum strip to the outer surface of the remaining longitudinal margin in order to form said lap seam; and (d) an extruded polyethylene jacket surrounding said aluminum strip and bonded to the outer surface thereof by said adhesive layer, said article forming a bendable tubular composite having an unsupported, non-kinking self-sustaining shape when bent.
