What does dark green color mean in a piping context?

In a piping context, the dark green color typically indicates that the piping system is used for saltwater. Color coding in piping systems is an essential practice that helps ensure safety and promote proper operation by clearly identifying the type of fluid contained within the pipes. Dark green is a standardized color that signals to personnel that the pipe carries saltwater, which is crucial for applications such as cooling systems, fire suppression systems, or other processes that utilize seawater.

Color coding allows for immediate recognition in maintenance and emergency situations, preventing potential hazards that could arise from mistaken identities of the systems, such as mixing fluids that should remain separate. Understanding these color codes is vital for anyone working in settings where various piping systems are present.
