Pipe Marker Size ChartLetter and Label Dimensions in accordance with pipe diameter. NOTE: It is recommended that pipes less than .75" in diameter be labeled with a permanent tag.

Pipe Marker Placement• Indicate direction of flow by labeling with arrows at one or both ends of the label• Visible from the point of normal approach • Near valves, flanges & changes in pipe direction • Both sides of ceiling, wall or floor penetrations • At any line entry or re-entry point• Every 25 feet to 50 feet is typical*• On straight pipe runs in intervals sufficient for identification• Ammonia Only: minimum of 1 per area through which the refrigeration piping passes *Every 40 feet for Ammonia pipe marking
