How often should I mark my pipes with pipe markers?

We often are asked how often should I mark my pipes with pipe markers, and its a good question, obviously you dont want to overdo it but pipe markers are not very useful if they can't be seen so the first point is they must be placed where they are easily visible.

Below we go over the different suggested locations of pipe markers as per the Australian Standard AS1345.

Straight Pipes

On straight lengths of pipe it is suggested that pipe markers are placed every 8 metres.

Wall & Floor Penetrations

Where a pipe goes through a bulkhead or wall you must place a pipe marker on both sides of the penetration.

Flanges & Valves

You must also place a pipe marker adjacent to all valves and flanges, these must be located on both sides of all valves and flanges.

Changes of Direction

On each side of a junction or elbow fitting you will need to add a pipe marker.

More about Australian Pipe Marking Standards

The Australian Standard 1345-1995 identifies the contents, direction of flow and safety parameters for pipes, conduits and ducts through colour coding. Pipe contents can include water, fluids, air, gases, electronics, and

communications wiring. It is not intended to apply to buried or normally inaccessible services. However, the general principles may be applied when considering those services.

Pipe Markers are a quick way to identify contents in a pipe, especially in emergency situations. Standards for Pipe Identification in Australia are outlined in AS 1345-1995.

A Pipe Marker is a label that shows what is inside the pipe and the direction it flows in. Simply cut off the arrow indicator that is not required and apply to the pipe.

Our pipe markers are made of self-adhesive vinyl and are available in 2 sizes.
