Home   >   Regulations  >  Pipe Marking

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 the fact your crew, is unaware 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 14726 specifies also additional colour codes that allow a more detailed identification of the substance.

How to install pipe marking?

Pipes must be marked in the following manner:
●   At least one in every room for every pipe and every substance
●   At each point where the pipes pass through a wall, a ceiling or floor
●   In the proximity of each valve and pump
●   Within a distance of 3 to 5 meters. Depending on the length of the pipe (local authorities can demand additional markers.)

Arrows to indicate the directional flow are advisable. Additional Identification by usage of text will avoid any confusion regarding the substance transported through the piping.

Pipe Marking Specials

We supply various types of special pipe markers who can fullfill all customer demands on FPSO, Ferries, Cruiseliners, Tankers and other types of ships. All markers will be made using the colours according to the ISO 14726 regulation or the customer’s demands.

Non-standard pipe markers can be delivered with an Self-Adhesive layer, or Non-Adhesive.

The non-adhesive pipe markers are called SnapOn Pipe Markers. The SnapOn Pipe Markers have the advantage that they are very quick to install, an can be removed and refitted on a different pipe. Also, they are ideal to fit oily or dirty pipes, since their snap-on feature doesn’t require them to stick to the pipe.
