Abstract

Methods and systems for a flexible hose assembly are provided. The flexible hose assembly includes a core tube including a substantially fluid-impervious body including an inner surface and an outer surface, and an aramid sleeve including aramid yarn, the aramid sleeve circumferentially covering the core tube.

Claims (16)

1. A flexible hose assembly comprising:

a core tube comprising a woven reinforced sleeve that is extruded with a material that is substantially fluid-impervious to form a body comprising an inner surface and an outer surface; and

an aramid sleeve comprising aramid yarn and a different second yarn interwoven with said aramid yarn such that the second yarn pads the aramid yarn, said aramid sleeve circumferentially covering the core tube.

2. An assembly in accordance with claim 1 wherein said material extruded with said woven reinforced sleeve is substantially impervious to a fuel between said inner surface and said outer surface.

3. An assembly in accordance with claim 2 wherein said fuel comprises a hydrogen carbon base.

4. An assembly in accordance with claim 1 further comprising at least a second aramid sleeve comprising aramid yarn, said at least a second aramid sleeve circumferentially covering the aramid sleeve, said second aramid sleeve being movable relative to said first aramid sleeve when said core tube is empty.

5. An assembly in accordance with claim 1 further comprising a polyester layer circumferentially covering said aramid sleeve.

6. An assembly in accordance with claim 5 wherein said polyester layer comprises a topcoat configured to facilitate making the polyester layer substantially impervious to at least one of liquid intrusion and ultraviolet light.

7. An assembly in accordance with claim 1 wherein said woven sleeve constitutes a polyester reinforcing sleeve co-extruded with urethane as said substantially fluid impervious material.

8. An assembly in accordance with claim 1 wherein said core tube is configured to maintain a substantially flat cross-section when empty and a substantially circular cross-section when at least partially filled with a fluid.

9. An assembly in accordance with claim 1 wherein each aramid sleeve comprising aramid yarn comprises circumferentially wound yarns interwoven with substantially longitudinally oriented yarns.

10. An assembly in accordance with claim 1 wherein each said aramid sleeve comprising aramid yarn comprises substantially continuous length multi-filament extruded yarns.

11. An assembly in accordance with claim 1 wherein said second yarn comprises polyester yarns interwoven with said aramid such that the polyester yarns pad the aramid yarns.

12. An assembly in accordance with claim 1 wherein said inner surface comprises a fluid friction coefficient having a value that is substantially similar to a fluid friction coefficient of a smooth-bore pipe.

13. An assembly in accordance with claim 1 wherein said core tube is capable of resisting pressure up to approximately 500 psig.

14. An assembly in accordance with claim 1 wherein said flexible hose assembly is capable of resisting pressure up to approximately 2250 psig.
