What does the color yellow signify in CSST gas piping systems?

In CSST (Corrugated Stainless Steel Tubing) gas piping systems, the color yellow specifically signifies that the pipe is intended to carry gas, which includes various types of fuel gas such as natural gas or propane. This color coding system helps to ensure safety by allowing for easy identification of the type of gas being transported, thereby reducing the risk of accidental mishandling or cross-connection with other types of piping systems.

Yellow is a standard color used in many jurisdictions for fuel gas lines, allowing both professionals and the public to recognize gas piping at a glance. This is essential in promoting safety measures in installations and maintenance of gas systems, where identifying the lines correctly is crucial for preventing hazardous situations.

In contrast, other colors are designated for different materials or uses. For instance, water supply lines may be painted in blue, while electrical pipes typically follow a different color scheme, such as green or red for potentially hazardous systems. Understanding and adhering to these color codes is vital for anyone involved in the installation, maintenance, or inspection of gas piping systems.
