Marine pipe markers

Safety & identification solutions

Marking pipes on ships and offshore sites is of the utmost importance to ensure safety at all times. Accidents, injuries and damage to machines and equipment can be caused by people’s ignorance of the substances that flow through pipes.

The ISO 14726 standard (International Standard Organization), specifies the principle colours for the identification of substances in pipes.

ISO (DIS)14726-2 specifies additional colour codes that allow a more detailed identification of the substance.

Pipes 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 floor.
In close proximity of each valve.
Every 3 to 5 metres (sometimes the local authorities will demand additional markers).
Arrows to indicate the directional flow are advisable
Additional identification by usage of text will avoid any confusion regarding the content of the pipes.

Blue		Fresh water
Brown		Fuel
Green		Sea water
Grey		Non-flammable gases
Copper		Masses (dry and wet)
