29、 Main colours may also be painted onto the pipeline on the total length. The markings shall be so positioned that the colour stripes (tapes) are perpendicular to the axis of the pipe. Additional colour markings may be added adjacent to a main colour marking on a pipe, when necessary, to distinguish
30、between pipes marked with the same main colour listed in Table 2, but carrying different types of medium (for example, a pipe carrying marine diesel oil and another pipe carrying heavy fuel oil). The area (or width) of additional colours shall be less than the area (or width) of main colours so that
31、 it is clearly apparent which are the main colours and which are additional colours. The marking shall be readily visible. It shall be arranged in such a way that the additional colour is surrounded by the main colour. Pipelines shall be marked as follows: once in each room, at least; at each penetr
32、ation point in bulkheads, walls and decks; close to each valve; within a distance of 3 m to 5 m of the length of the pipeline, whereby the local conditions may require a more frequent marking due to pipe bends or the close proximity of pipes for different services. Paints and adhesives of self-adhes
33、ive identification labels or coloured tapes shall neither attack nor damage the surface of the pipe components that are to be marked. 5.2 Marking of pipes with tapes Pipes of up to 200 mm outer diameter: the tapes comprise the entire circumference of the pipes and are adhered at their ends by overla
34、pping. Pipes of more than 200 mm outer diameter: the tapes comprise about half the circumference of the pipes. Pipes in bundles: shall be individually marked. If the marking is not possible over the entire circumference, an abbreviation of the marking is admissible. A common marking of several pipes
35、 with the same content or function is only admissible on collars. 9 DIN ISO 14726:2010-10 5.3 Supplementary indications Arrows to indicate the direction of flow in a pipe are recommended. Pipes with flow in opposite directions at different times may be marked with arrows pointing in opposite directi
36、ons. Additional marking by text is also recommended to signify unambiguously the content and/or function of the pipe. When additional markings by text are used, consideration should be given to the use of a language understood by the crew members whose responsibilities include being able to identify
37、 pipes and piping systems. 10 DIN ISO 14726:2010-10 Annex A (informative) Explanations for some media/functions A.1 Waste media A.1.1 Description This includes all media that contain dirt or other foreign substances.
