Pipe Markers & Labels

Pipe Markers and Labels

Pipe markers and identification labels make it clear what's flowing through a pipework system — water, gas, chemical, steam, or process fluid — so maintenance teams, contractors, and emergency responders can identify pipe contents at a glance. In Australia, pipe identification is governed by AS 1345 (the standard for identification of contents of pipework, conduits, and ducts). AIMS Industrial stocks pipe markers and labels compliant with the standard for industrial, plumbing, and process applications.

What AS 1345 specifies

AS 1345 prescribes the colour codes, lettering sizes, and marker placement for pipe identification across categories — water (green), steam (silver), oils (brown), gas (yellow ochre), acids/alkalis (violet), air (light blue), other liquids (black), fire-fighting (red). The standard ensures consistent identification across sites and industries, which matters for safety, maintenance, and regulatory compliance.

The product types we stock

• Pre-printed pipe markers — wrap-around vinyl markers in the AS 1345 colours and lettering for common pipe contents
• Pipe identification arrows — directional flow arrows to indicate fluid direction
• Custom pipe markers — for specific contents not covered by stock pre-prints
• Self-adhesive labels — for smaller-diameter pipes where wrap-around markers aren't practical
• Marker holders and frames — for areas where labels won't adhere directly to pipework

Sizing and placement

Marker size scales with pipe diameter — small pipes need shorter markers, larger pipes need correspondingly larger ones for legibility. AS 1345 specifies minimum lettering height by pipe size; check the standard for the exact requirements. Markers should be placed where the pipe runs are most visible: at intersections, near valves, on either side of walls or floors, and at regular intervals on long runs.

Brands stocked at AIMS

Brady is the established brand for industrial identification — pipe markers, valve tags, lockout/tagout, safety signs. The Brady pipe marker range covers the AS 1345 colour codes and is engineered for industrial conditions: UV-stable inks, weather-resistant adhesives, and durable vinyl construction that survives years of outdoor and indoor service.

Why bother with proper markers

Properly identified pipework is a safety asset. Maintenance crews spend less time tracing systems; emergency responders can isolate the right service quickly; new staff and contractors can navigate the site without dangerous assumptions. The cost of a comprehensive pipe marker setup is small against the cost of one wrong-pipe incident.
