Pipe identification allows for improved emergency response times and a professional appearance. Brady's range of Pipe Identification products are designed in accordance with AS1345-1995 and enable quick recognition of pipe contents.

Understanding AS 13745-1995 "Identification of the contents of pipes, conduits, and ducts"

Why Mark Pipes?

Pipe markers aid in the quick identification of a pipe's contents - especially in an emergency situation. A successful pipe identification program helps employees, contractors, and emergency responders to identify a pipes contents where there are several pipes side by side. Pipe markers also save valuable time when tracing lines are necessary during maintenance.

Where Should Pipe Markers Be Located?

AS 1345 specifies that markers be placed adjacent to all junctions, valves, service applicances, bulkheads and wall penetrations. Markers shall be spaced no more that 8 metres apart except for long, uninterrupted straight runs of external services where spacing shall not exceed 50 metres.

Marker Design/Layout Requirements:

AS 1345 addresses several elements of pipe marker design including Marker Layout: A marker is comprised of a printed word or words on a coloured background with a contrasting border and chevron to show direction of flow. 

Marker Colours:

The legend and background colours of a pipe marker are determined by the pipe's contents and are specified according to the tables in the PDF document attached to this article. 


Additional information about the contents of a pipe is communicated through the use of supplementary warning colours (outlined in the PDF document attached to this article). Supplementary colours are sold separately as a wrap-around band, or can be printed on custom markers at the time of manufacture
