Abstract

A heated whip hose ( 10 ) includes a hose core ( 12 ) configured to deliver a fluid, a heating element ( 16 ) disposed around the hose core, a protective layer ( 20 ) disposed around the heating element and hose core, an insulating layer ( 22, 24 ) disposed around the protective layer, and an abrasion protection layer ( 26 ) disposed around insulating layer and forming an outer sheath.

First claim

1 - 41 . (canceled)

42 . A heated whip hose comprising:
a first end configured to couple to a main hose; a second end opposite the first end, the second end configured to couple to a fluid delivery device; a hose core configured to deliver a fluid from the first end to the second end; and a heating element disposed around a partial length of the hose core to form a heated section and an unheated section, wherein the heated section extends from the first end and wherein the unheated section extends from the second end.

43 . The heated whip hose of claim 42 , and further comprising:
a protective layer disposed around the heating element and hose core; an insulating layer disposed around the protective layer; and an abrasion protection layer disposed around the insulating layer and forming an outer sheath.

44 . The heated whip hose of claim 43 , wherein the protective layer is a self-vulcanizing material.

45 . The heated whip hose of claim 43 , wherein the insulating layer comprises a thermal insulating layer formed of a heat-resistant fiber material.

46 . The heated whip hose of claim 45 , wherein the insulating layer further comprises a radiant heat insulating layer disposed around the thermal insulating layer.

47 . The heated whip hose of claim 46 , wherein the radiant heat insulating layer is a foil-lined material and wherein a reflective foil surface faces the hose core.

48 . The heated whip hose of claim 42 , wherein the heating element is a sheathed electrically conductive wire.

49 . The heated whip hose of claim 42 , wherein the unheated section extends a length up to about 72 inches from the second end.

50 . The heated whip hose of claim 42 , wherein the unheated section extends a length less than about 24 inches from the second end.

51 . The heated whip hose of claim 50 , wherein the unheated section extends a length greater than about 6 inches from the second end.

52 . The heated whip hose of claim 42 , wherein the unheated section extends a length of about 12 inches to 18 inches from the second end.

53 . The heated whip hose of claim 42 wherein the unheated section extends a length selected from the lengths consisting of 6-12 inches, 12.1-18 inches, 18.1-24 inches, 24.1-30 inches, 30.1-36 inches, and 36.1-42 inches from the second end.

54 . The heated whip hose of claim 42 , wherein the heating element is helically wound around the hose core.

55 . The heated whip hose of claim 54 , wherein the heating element is wound with a uniform pitch.

56 . The heated whip hose of claim 54 , wherein the heating element includes a turn at the unheated section and wherein first and second ends of the heating element are located at the first end of the whip hose where the heating element is coupled to an electrical connection.

57 . The heated whip hose of claim 42 , wherein the heating element has a first end and a second end and wherein each of the first end and the second end is located at the first end of the whip hose where the heating element is coupled to an electrical connection.

58 . A heated whip hose assembly comprising:
a first whip hose and a second whip hose, each of the first and second whip hoses comprising:
a first end configured to couple to a main hose;
a second end opposite the first end, the second end configured to couple to a fluid delivery device;
a hose core configured to deliver a fluid from the first end to the second end; and
a heating element disposed around a partial length of the hose core to form a heated section and an unheated section, wherein the heated section extends from the first end and wherein the unheated section extends from the second end.

59 . The heated whip hose assembly of claim 58 , wherein the heating element has a first electrical connection at a first end and a second electrical connection at a second end, wherein the first and second electrical connections are located at the first end of each of the first and second whip hoses.

60 . The heated whip hose assembly of claim 59 , wherein the second electrical connection of the first whip hose is electrically connected to the second electrical connection of the second whip hose.

61 . The heated whip hose assembly of claim 58 and further comprising:
a protective layer disposed around the heating element and hose core;
a first insulating layer disposed around the protective layer configured to direct radiant heat from the heating element toward the hose core; and
an abrasion protection layer disposed around insulating layer and forming an outer sheath of the whip hose.
