What Color are Steam Pipes?

The American National Standards Institute (ANSI) A13.1 1996 standard for pipe identification specifies that steam pipes should be identified with a yellow background color with bold black text. This color code is widely recognized and used in many industrial and commercial settings to identify the contents of a pipe as steam.

The ANSI A13.1 standard provides a consistent and standardized system for the identification of pipes, valves, and other equipment throughout a facility. This helps to reduce confusion and improve safety by making it easy for workers to quickly identify the contents of a pipe and take the necessary precautions.

In addition to the color code, the standard also specifies the use of specific wording and lettering to identify the contents of a pipe. For example, pipes carrying steam should be marked with the word “STEAM” in black letters on a safety yellow background. This further helps to ensure that the contents of a pipe are clearly identified and handled safely.

It’s important to note that the ANSI A13.1 standard is widely recognized in the United States, but other countries may have different regulations and standards for pipe identification. Being aware of all local regulations regarding workplace safety in general, and pipe marking specifically is critical for protecting everyone in an area.

Overall, the ANSI A13.1 standard for pipe identification is an important tool for improving safety and reducing confusion in industrial and commercial settings. The use of a safety yellow background color with bold black text for steam pipes is a widely recognized and standardized practice that helps to ensure the safe handling of steam pipes.
