Pipe Marking and Labeling


Marking and identification of pipe contents and piping systems is important to safety and maintenance in industry. Pipe Markers are to visibly identify what's flowing inside - gas, liquid, or solid particles, the flow direction, and degree of hazard in a piping system.

Pipe Markers provide visible information to communicate the start, run, and end of contents in piping systems. A comprehensive and standardized labeling program - when installed properly provides an awareness of hazards in piping systems, thus, promoting a safe working environment - minimizing the potential for downtime due to unknown pipe contents that may lead to an error or accident.

The legend or wording on the pipe marker is the primary means of naming the contents of the pipe. The name is to be brief, yet complete or in understood abbreviated format. Arrows are to accompany the legend to indicate the directional flow of the contents. Additional information may be necessary to identify the content details such as pressure and temperature.

Installation recommendations:

  • Above or below center visual line of pipe
  • Frequent intervals on straight pipe runs (visible from any point along the length)
  • Close to valves
  • Near branches and T’s in piping
  • Any change in direction of piping
  • Near points before and after pipe going through walls, ceilings, and floors
