Underground Pipe Markers

Pipeline markers communicate critical information including the type of material transported (gas, water, chemicals, electrical conduit), flow direction, pressure levels, and any associated hazards. For underground pipes, surface markers also indicate burial depth and the responsible utility or facility owner, helping prevent accidental strikes during excavation work.

Underground pipe color codes follow APWA (American Public Works Association) standards: red for electric power, yellow for gas or oil, orange for communications, blue for potable water, green for sewer lines, purple for reclaimed water, and pink for temporary survey markings. These color codes help excavators and utility workers quickly identify buried line types and avoid dangerous strikes.

Yes. OSHA and ANSI/ASME A13.1 standards govern pipe marking requirements, including color coding, label size, and placement frequency. Shield and Supply's labeling systems and industrial labels are designed to meet these compliance standards, and the included LabelSuite™ software provides pre-configured templates to ensure every marker meets regulatory requirements.

Shield and Supply's industrial vinyl labels are engineered to last 5–10 years indoors or outdoors. They are scratch-resistant, chemical-resistant, and weatherproof, making them suitable for harsh underground or surface-level environments exposed to moisture, UV light, solvents, and extreme temperatures. Specialty materials like reflective or high-temperature vinyl are also available.
