Product Information


Oxygen 50 Psi Wrap Around Pipe Marker meet specification compliances for ANSI / ASME A13.1 standards for the identification of pipes. Oxygen 50 Psi Wrap Around Pipe Marker are available in wrap-around and strap-on formats for pipe outside diameters ranging from 3/4 inch to over ten inches and provide 360 degree visibility. 2 nylon ties are included with all markers for pipes with an outside diameter of 6-1/8" and larger so they can be easily affixed to the pipe.


Snap-Around Medical Gas Pipe Markers

These markers are made with high-quality PVC vinyl and printed with UV-resistant ink for maximum durability and are available in a convenient snap-around (coiled) format for easy application. These markers are simply uncoiled by hand and automatically recoil around the pipe for a secure fit.

Marker Size, Letter Height & Max. Characters Per Marker

The following shows the recommended pipe marker letter height and marker size based on the outside pipe diameter of the pipe to be identified. For pipes smaller than 3/4" and for valve identification, the use of a permanent legible tag is recommended.

Latest Revision ANSI / ASME A13.1

ANSI / ASME is the most common pipe identification standard used in the United States. The standard specifies the primary and secondary means of identifying pipe content, as well as the size, color and placement of the identification device.

1. Primary Identification

The legend (name of pipe content) and directional flow arrow remain the primary means of identifying pipe content. The size and placement of the marker and arrow has not changed. See ANSI / ASME size table and installation recommendations for details.

Legends should use arrows to indicate the direction of flow, where flow can be in both directions, arrows in both directions should be displayed. Contents should be identified by a legend with sufficient additional details such as temperature, pressure, etc. Legends should be brief, informative, pointed, and simple for greatest effectiveness.

1.1 Additional Means of Identification ASME A13.1

ASME A13.1 incorporated the GHS pictograms into the 2015 revision and has recommended their use as part of the legend.

"The applicable GHS pictograms as illustrated in Fig.1 may be included as part of the legend. Where piping is connected to containers that are labeled in accordance with GHS requirements, a corresponding label on the piping may be provided. The corresponding label should contain at least the product name or identifier, the pictogram, the signal word, and the physical, health, and environmental hazard statements."

2. Secondary Identification

ASME A13.1 4.2 Color: "Color should be used to identify the characteristic hazards of the contents. Color should be displayed on, or contiguous to, the piping by any physical means, but its use shall be used in combination with a legend. Color may be used in continuous, total-length coverage or in intermittent displays. Colors preceded by the word "Safety" shall meet the requirements of ANSI / NEMA Z535.1"

Flammable Fluids
Used for fluids that, under ambient or expected operating conditions, are a vapor or procedure vapors that can be ignited and continue to burn in air. The terms thus may apply, depending on service conditions, to fluids defined for other purposes as flammable or combustible
Oxidizing Fluids
Oxidizing fluid is any gas or liquid that may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does.
Fire Quenching Fluids
This classification includes water, foam and CO2 used in sprinkler systems and fire fighting piping systems.
Toxic & Corrosive Fluids
This classification includes fluids that are corrosive or toxic, or will produce corrosive or toxic substances when released.
Combustible Fluids
This classification includes fluids that can burn but are not flammable.

3. Placement

  • Marker visibility

Always position pipe labels on pipes to achieve the best visibility. Install pipe labels below or above the horizontal centerline of the pipe when pipes are located above or below the normal line of vision.

  • Pipe marker illustration
    Install pipe labels close to valves or flanges.
  • Plastic Lockout Hasp 428 C3504
    Apply pipe labels adjacent to changes in direction and/or branches.
  • Marker installation options
Install pipe labels before and after all wall, floor and ceiling penetrations.
  • Marker installation options
Install pipe labels at frequent intervals on straight pipe runs Brimar recommends 20 to 25ft.

4. Abandoned Piping

Piping that has been abandoned in place should be identified. The recommended color scheme is a safety white background with black letters. A black border should be added to the identification. When the abandoned piping is protected from corrosion by the addition of a pressurized fluid or contains residual hazardous material, the legend should indicate that.
