Chemical Resistant and Durable Vinyl Pipe Markers

ANSI / ASME Standard A13.1-2007

The ANSI / ASME Standard for pipe identification is a widely used guideline in determining pipe identification requirements. The purpose of the standard is to “assist in identification of hazardous materials conveyed in piping systems and their hazards when released into the environment. Pipes are defined as conduits for the transport of gases, liquids, semi-liquids or fine particulate dust.”

Custom Pipemarker Quotation Request

These high-quality pipemarkers are printed on pressure-sensitive vinyl which is chemical resistant and resists fading and scratching. It is recommended that pipes should be marked at both sides of floor or wall penetration, adjacent to changes in direction, adjacent to all valves and flanges and every 25’ to 50’ intervals on straight runs. Stock GHS ANSI A13.1 and Canadian CGSB Standards. Both of these standards comply with GHS within OSHA and WHMIS.

ICC Compliance Center stocks all pure chemicals with the proper names, direction arrows and classification.
