<p>The invention relates to a pipe (1) suitable for transporting at least two different fluids, which pipe (1) is provided with at least one mark (2a) extending in the longitudinal direction of the pipe (1), which functions to indicate the nature of the fluid for the transport of which the pipe (1) is arranged, said pipe (1) being provided at least with a second mark (2b) extending in the longitudinal direction of the pipe (1), which functions to indicate a second fluid for the transport of which the pipe (1) is suitable. This aspect leads to a simplification as regards logistics; if a particular pipe quality can be used for the transport of drinking water and gas, for example, only one type of pipe needs to be kept in stock. Upon use of the pipe (1), one of the two marks (2a,2b) may be removed or be moved to the rear side, making it "inactive", as it were. This can be achieved, for example, by positioning the pipe (1) with the applicable mark (2a,2b) on the front side, i.e. the side from which the pipe (1) is approached, so that the mark (2a,2b) in question will be the first mark that is detected when the pipe (1) is approached at a later point in time. <IMAGE></p> |
