Med. Press. Steam High-Performance Snap-Around & Strap-On Pipe Marker are used to identify piping systems in industrial environments that are expected to reach higher temperatures or harsh exposure to chemicals. High-Performance Snap-Around & Strap-On Pipe Markers meet specification compliances for ANSI / ASME A13.1 standards for the identification of pipes. No pipe preparation is needed for these markers. Med. Press. Steam High-Performance Snap-Around & Strap-On Pipe Marker are available in wrap-around and strap-on formats for pipe outside diameters ranging from 1/2 inch to over ten inches and provide 360 degree visibility.

High-Performance Pipe Markers
These markers are designed to withstand harsh chemicals, abrasion, and all weather conditions. The printed legend is laminated between two layers of polyester, creating an extremely durable product. These markers are available in 2 different types: snap-around markers that easily snap into place around a pipe, and strap-on markers that are helpful for labeling pipes with a large diameter.
For pipe diameters 1/2″ through 7-7/8″, use snap-around markers (Styles 4A, 4B, 4E, 4F); these markers will wrap around pipes and are secured in place by an overlapping clear adhesive strip.
For pipe diameters 8″ or larger, use strap-on markers (Styles 4G and 4H). These markers are laminated to a heat and chemical-resistant carrier that is then strapped onto a pipe with nylon ties or stainless steel strapping (ties and strapping are sold separately).

Marker Size, Letter Height and Maximum Characters per Marker
The following chart 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.

High-Performance Pipe Marker Styles
Colors:
The secondary means of identification is the color code of the marker. The exact colors are contained in the ANSI Z535.1 Safety Color Code.
Color is the secondary means to identification but many times the most important. The color of the marker should be used to identify the characteristic hazard of the contents of the pipe. The following chart list the classifications shown by ANSI / ASME A13.1 2015 as the suggested color combinations for the pipe markers.

Placement
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.
