Flexible hose article and related methods
View Patent ↗The present invention generally relates to flexible hose articles and methods. Some embodiments include hoses that can be reversibly bent and/or shaped. Furthermore, some embodiments can comprise methods for making and/or using such hose articles.
1. A hose article, comprising: a pair of longitudinally joined helical wires defining a double helix; and at least one containment layer in contact with the pair of helical wires, wherein the at least one containment layer comprises: at least one layer disposed radially inward relative to the pair of helical wires; and at least one layer disposed radially outward relative to the pair of helical wires, and wherein the at least one layer disposed radially inward comprises a material selected from the group consisting of chlorosulfonated polyethylene, chlorosulfonated polyethylene/chlorinated polyethylene blends, hydrogenated nitrile rubber, nitrile rubber, polychloroprene, chlorinated polyethylene acrylonitrile-butadiene polymers, styrene-butadiene polymers, polyisoprene, polybutadiene, ethylene-propylene-diene terpolymers, chlorinated polyethylene, natural rubber polymers, propylene/ethylene-propylene rubber blends, and combination thereof.
2. The article of claim 1 , wherein one or more of the helical wires comprise a gauge from about 0.045 inches to about 0.500 inches.
3. The article of claim 1 , wherein one or more of the helical wires comprise a material selected from the group consisting of steel, spring steel, stainless steel, and aluminum.
4. The article of claim 1 , wherein the pair of helical wires define a pitch from about 130 windings per foot to about 0.1 windings per foot.
5. The article of claim 1 , wherein the pair of helical wires is joined by a means selected from the group consisting of welding, brazing, and binding.
6. The article of claim 1 , wherein the pair of helical wires comprises a pair of helical wires.
7. The article of claim 1 , wherein the hose defines an internal diameter from about 2 inches to about 24 inches.
8. A hose article, comprising: a pair of longitudinally joined helical wires defining a double helix; and at least one containment layer in contact with the pair of helical wires, wherein the at least one containment layer comprises: at least one layer disposed radially inward relative to the pair of helical wires; and at least one layer disposed radially outward relative to the pair of helical wires, and wherein the at least one layer disposed radially, outward comprises a material selected from the group consisting of chlorosulfonated polyethylene, chlorosulfonated polyethylene/chlorinated polyethylene blend, hydrogenated nitrile rubber, nitrite rubber, polychloroprene, chlorinated polyethylene acrylonitrile-butadiene polymers, styrene butadiene polymers, polyisoprene, polybutadiene, ethylene-propylene-diene terpolymers, chlorinated polyethylene, natural rubber polymers; propylene/ethylene-propylene rubber blends, and combination thereof.
9. The article of claim 8 , wherein one or more of the helical wires comprise a gauge from about 0.045 inches to about 0.500 inches.
10. The article of claim 8 , wherein one or more of the helical wires comprise a material selected from the group consisting of steel, spring steel, stainless steel, and aluminum.
11. The article of claim 8 , wherein the pair of helical wires define a pitch from about 130 windings per foot to about 0.1 windings per foot.
12. The article of claim 8 , wherein the pair of helical wires is joined by a means selected from the group consisting of welding, brazing, and binding.
13. The article of claim 8 , wherein the pair of helical wires comprises a pair of helical wires.
14. The article of claim 8 , wherein the hose defines an internal diameter from about 2 inches to about 24 inches.
