Marine Pipe Marking Standards, Labels and Tape

Industrial Marine Marking Tape Instructions

Marine shipPipes must be marked in the following manner:

  • At least once in every room
  • At each point where the pipes pass through a wall, a ceiling, or a floor
  • Close to each valve
  • Within a distance of 3 to 5 meters, depending on the length of the pipe, unless more are needed due to pipe bends or proximity to other pipes
  • Bundled pipes should be labeled individually
  • For pipes 200mm in diameter or less, the label should take up the entire circumference of the pipe
  • For pipes greater than 200mm in diameter, the label should take up about half of the circumference of the pipe
  • Use arrows to indicate the direction of the flow (pipes with flow in opposite directions at different times may be marked with arrows pointing in opposite directions)
  • Text can be used in addition to color to signify the content • Color stripes should be placed perpendicular to the pipe axis

Best Label Printer and Tape option:

Marine Pipe Marking Standards have main colors (defined by ISO 14726) to indicate groups of similar substances. Additional color bars (defined by ISO/DIS 14726-2) are added to indicate specific substances. The additional color should be surrounded by the main color and have a width smaller than that of the main color.

Marine Color Specifications to Meet Compliance

Marine Piping Color Coding

Marine piping color coding is crucial for compliance with industry standards. The International Organization for Standardization (ISO) has established guidelines (ISO 14726) for main colors and additional color bars used in marine pipe marking. The main colors represent groups of substances, while additional color bars indicate specific substances. Labels should be placed at specific locations, such as in each room, at pipe entry/exit points, near valves, and at appropriate intervals for longer pipes. The labels should be durable and weather-resistant in marine environments. Proper pipe marking enhances safety, maintenance, and emergency response procedures in the marine industry.
