Safety Marking Tapes
IMO Pipemarking Tapes - Marine Pipe Identification Tape - acc to ISO 14726
General Description
Pipeline identification on board ships is very important for safety reasons, especially for the safety of the entire crew. The medium flowing through the the pipework can cause a lot of damage, and be dangerous to the people on board the ship during an emergency or in case of pipework damage. The appropriate marking makes it possible to identify the type of danger we are dealing with during the emegency and to take the steps to get rid of it.

The International ISO14726-1 (year 1999) standard defines the basic colours which should be used for pipeline identification on board ships.
Another regulation, ISO 1476-2 (year 2002) specifies additional colours which can be used together with the main colours for a more thorough marking of the medium flowing through the pipework.
The table included in this broshure presents the basic colours and also all the available permutations of identification colours in accordance with the ISO14726-2 (year 2002) norms.
Availability
The identification tapes are available in two systems:
Multi-colour system - tapes with the colour combination printed on it - this system is the easiest to install.
Single-colour system - tapes from which you can make any number of colour combinations by yourself, this is a more economical and flexible solution, however, the installation takes longer to complete.
All types of tapes are available at following standard sizes:
40 mm x 25 m
70 mm x 25 m
160 mm x 25 m
Considering many size standards available on the market we can manufacture any particular size for you.
Installation
- Each pipe should be marked at least once in each separate room.
- The best places for installing the identification tapes are: close to the objects like valves, filters or tanks, exits passing through the walls or cellings, close to the room entrances.
- All surfaces must be thoroughly cleaned before applying the identification tapes.
- During the application tape should be overlaped 3-4 cm beyond the starting edge.
