Unmarked pipes could mean danger for both your workers and your facility. Workers must be made aware of where pipes are, what they are carrying, and any associated risks. Pipe marking regulations offer both placement and color recommendations, and help create a system that is easy to understand and work with.
Start by creating a list of all pipe contents in your facility, documenting the following:
- Pipe contents
- Outside diameter of pipe (including insulation)
- Quantity of markers needed per ASME/ANSI standards
- To/from information
- Location details (for aid in installation)
From there, you can determine which pipe marking products are needed, using the guidelines below.
- SIZE SPECIFICATIONS – ANSI standards also designate letter height and length of colour field for various pipe diameters:
- LOCATIONS – the four key areas where pipes need to be marked are: adjacent to changes in direction, adjacent to all valves and flanges, at both sides of floor or wall penetrations, and at 25- to 50-foot intervals on straight runs
Additional Tips & Resources
- Display markers on all visible sides of the pipe
- Use in conjunction with pictograms where recommended
- Apply Self-Adhesive Markers to clean, dry surfaces or use Snap-Around Markers if pipes are very dirty
