What does the tan color indicate in piping systems?

The tan color in piping systems is typically used to indicate low pressure air. This color coding is part of a safety and operational standard that facilitates the quick identification of the type of fluid or gas transported by the pipes. In many facilities, consistent color codes help personnel recognize and respond appropriately to different systems, thereby minimizing the risk of accidents or confusion during maintenance and operations.

In the context of blueprints or physical piping installations, the use of tan for low pressure air aligns with established practices. By differentiating low pressure air from other systems through color coding, personnel can effectively avoid mistakes, especially in complex environments where multiple systems intersect.

Other systems like steam, saltwater, and sewage often use different color codes that are well-defined in industry standards, and recognizing the tan color specifically denotes low pressure air, ensuring that operators can handle the system correctly and safely.
