Abstract
A duct includes a polymeric duct wall that circumscribes a fluid-conveyance passage. The polymeric duct wall includes, relative to the fluid-conveyance passage, an inner surface and an outer surface. An electrically conductive coating is disposed on at least one of the outer surface and the inner surface.
Claims19
A duct comprising:
- a polymeric duct wall circumscribing a fluid-conveyance passage, the polymeric duct wall including, relative to the fluid-conveyance passage, an inner surface and an outer surface;
- and
- an electrically conductive coating disposed on at least one of the outer surface and the inner surface.
A duct comprising:
- a non-electrically conductive duct wall circumscribing a passage, the non-electrically conductive duct wall including, relative to the passage, an inner surface and an outer surface, at least one of which collects electric charge;
- an electrically conductive coating disposed on the surface and which collects the electric charge;
- and
- an electrically conductive bridge extending from the inner surface to the outer surface, the electrically conductive bridge dissipating the electric charge from the electrically conductive coating to a grounded component.
