Pipe Markings - ANSI/ASME

ANSI/ASME Standard

Schemes for identification of the contents of piping systems have been developed in order to promote greater safety and lessen the chances of error, confusion, or inaction, especially in times of emergency.

A uniform system for the identification of piping contents has been established to warn personnel when the piping contents are inherently hazardous.

Therefore, while this Standard has been prepared to specify the identification of the contents of piping systems on the basis of legends, it also suggests the use of color as a supplementary means of identifying the type of hazard of the material contained in the system.

Object and Scope of ANSI Pipe Markings

This Standard of ANSI Pipe Labeling is intended to establish a common system to assist in identification of hazardous materials conveyed in piping systems and the materials’ hazards when released in the environment. This scheme concerns identification of contents of piping systems.

It is recommended for the identification of piping systems used in industrial, commercial, and institutional installations, and in buildings used for public assembly.

It does not apply to buried pipelines nor to electrical conduits.

Existing schemes for identification shall be considered as meeting the requirements of this Standard if

(a) such schemes are described in writing

(b) employees are trained as to the operation and hazards of the piping systems
