    Abstract: A metallic pipe (19) for the transport of fluid, about which is arranged a protective insulating layer (17). An outer conductive or semi-conductive outer layer (18) is extruded about the protective insulating layer (17). According to one aspect of the invention, a method of detecting damage to the protective insulating layer is provided, comprising performing an electrical test where voltage is applied between the metallic fluid pipe (19) and the outer conductive or semi-conductive layer (18). Voltage drops or voltage instability or current flow indicate structural damage to the protective insulation layer (17).
