ANSI/ASME A13.1 Pipe Marking Reference
Brady pipe markers are designed to comply with ANSI/ASME A13.1, the standard for identification of piping systems. Key requirements include:
- Color coding by fluid class: Yellow/Black = Flammable, Combustible, or Oxidizing fluids — including diesel oil and other petroleum products
- Size B marker (0.875 in H, 0.75 in character height) is required for pipes with 1.5–2.375 in outside diameter per ANSI/ASME A13.1 sizing requirements
- Marker placement: Adjacent to all valves and flanges, at both sides of floor/wall penetrations, adjacent to changes in direction, and every 25–50 ft on straight runs
BradySnap-On vs. Other Brady Pipe Marker Styles
The BradySnap-On (B-915 plastic) is a non-adhesive coiled marker that snaps around the pipe for 360° visibility and is easily removable and reapplicable. It fits pipes 0.75–6 in OD across sizes A–D and offers 5–8 years outdoor durability. It can be applied to dirty, oily, greasy, or rough surfaces where adhesive markers would not adhere. For larger pipes (over 6 in OD), Brady Strap-On markers are recommended. For permanent adhesive applications, Brady self-sticking vinyl markers are available.
Frequently Asked Questions
What pipe diameter does the Brady 4174-B fit?
The 4174-B is a size B marker designed for pipes with an outside diameter of 1.5–2.375 inches. The same "Diesel Oil" legend is available in other sizes (A through H) to cover a full range of pipe ODs. Contact MTE Solutions for the correct size for your pipe diameter.
Why is the Brady 4174-B black on yellow?
Per ANSI/ASME A13.1, black on yellow is the required color scheme for pipes carrying flammable, combustible, or oxidizing fluids — including diesel oil. The yellow background with black text provides high visibility and immediately communicates the hazard class of the pipe contents to facility personnel.
How does the BradySnap-On marker install?
The BradySnap-On marker is a coiled plastic marker that installs tool-free by snapping around the pipe. No adhesive, strapping, or tools are required. It provides 360° visibility and can be repositioned or removed without leaving residue — ideal for pipes where adhesive markers are not practical or where periodic repositioning is needed.
Is the Brady 4174-B suitable for outdoor use?
Yes. The B-915 plastic construction provides 5–8 years average outdoor durability with a service temperature range of -40°F to 140°F. It is abrasion-resistant and chemical-resistant, suitable for exposed outdoor diesel fuel pipe marking applications.
Does the Brady 4174-B meet ANSI/ASME A13.1 requirements?
Yes. Brady BradySnap-On pipe markers are designed to meet ANSI/ASME A13.1 requirements for pipe identification, including correct color coding, legend, character height, and marker size for the applicable pipe diameter range.
