Abstract
A ventilation system for insulated pipe or pipeline to prevent corrosion thereof is discussed. The ventilation system can include an outer skin wrapped around the insulated pipe or pipeline, the outer skin separated from the insulation pipe by stand-off supports to form an annular chamber within the system. The system has a vent screen along a bottom side of the outer skin and a gable running along the top side of the outer skin, the gable having a number of openings therethrough to allow air to flow in through the vent screen, through the annular chamber and out through the gable openings, drawing moisture from the insulation thereby preventing corrosion of the pipe or pipeline.
Claims10
A ventilation system for insulated pipe, the system comprising:
- a) an outer skin circumferentially disposed around the insulated pipe, thereby forming an annular chamber between the insulated pipe and the outer skin;
- b) a plurality of stand-off supports disposed between the insulated pipe and the outer skin in the annular chamber;
- c) a gable disposed on an upper side or portion of the outer skin, the gable disposed at least partially along a length of the outer skin, and wherein the gable further comprises a plurality of openings therealong to provide communication between the annular chamber and an exterior of the system;
- and
- d) a vent opening disposed at least partially along a lower side or portion of the length of the outer skin.
A method for providing ventilation around an insulated pipe, the method comprising:
- a) placing a plurality of stand-off supports circumferentially around the insulated pipe at spaced-apart locations along a length of the insulated pipe;
- b) placing an outer skin circumferentially around the insulated pipe wherein the outer skin is supported by the plurality of stand-off supports to form an annular chamber between the insulated pipe and the outer skin, wherein the outer skin further comprises:
- i) a gable disposed on an upper side or portion of the outer skin, the gable disposed at least partially along a length of the outer skin, and wherein the gable further comprises a plurality of openings therealong to provide communication between the annular chamber and an exterior of the system, and
- ii) a vent opening disposed at least partially along a lower side or portion of the length of the outer skin.
