Pipe Marking
Basic
instructions for pipe label design, and placement will help to improve facility
efficiency and increase safety through visual communication.
Pipe Marking Importance
·
Safety-Eliminate
accidents by minimizing identification errors.
·
Efficiency-No
wasted time tracing pipes to their source.
·
Compliance -
Reduce company liability and eliminate fines.
PIPE IDENTIFICATION STANDARD
The standard
specifies the primary and secondary means of identifying pipe contents, as well
as the size, color and placement of the identification device.
PRIMARY PIPE IDENTIFICATION
The text legend (name of pipe
content) and directional arrow remain the primary means of identifying pipe
contents. Attaching arrows at one or both ends of the marker indicates flow
direction. See the ANSI/ASME size chart and installation guide in the following
sections for more details.
SECONDARY PIPE IDENTIFICATION
A secondary means of pipe marker
identification is the color code of the marker. The terminology of inherently
hazardous or nonhazardous has been removed from the standard, effective since
2007.
Other significant color changes
in 2007 included the addition of Brown/White for combustible fluids and
Orange/Black for toxic or corrosive fluids. The standard also identified
four additional “defined by user” color combinations for additional customization
options on non-standard markers. Those exact colors are the recommended safety
colors contained in the ANSI Z535.1 standard.
The updates to ANSI/ASME
A13.1-2015 added oxidizing fluids to the definitions for Yellow/Black, but did
not add any new colors to the standard.
HOW TO PROPERLY LABEL PIPES
- Obtain a legend list of all pipe contents in your plant.
- Collect the following data on your piping systems (this may require tracing lines to determine quantities and sizes):
– Pipe contents
– Outside diameter of pipe (including insulation)
– Quantity of markers needed per ASME/ANSI A13.1 or other
standards
– Pressure
– Temperature
– To/From information
– Location of specific legends by area (for aid in installation)
***Note: You may be able to use blueprints or P&IDs if they
are current instead of walking down all of your lines. Seton also offers
Take-Off Services to help you determine your pipe marking needs.
- Select
color of marker.
Other color codes may also be acceptable, as long as your
choices are consistent and documented, and the affected workers are trained to
understand the system.
Use clear and simple terms to identify the contents of each
pipe.
Text should be easy to read from a distance
Use a sans-serif font such as Arial or Helvetica

Hi there! I could have sworn I've been to this website before but after checking through some of the post I realized it's new to me. Anyhow, I'm definitely happy I found it and I'll be book-marking and checking back often!fall protection system
