The color white in piping systems typically signifies steam. This color coding is part of a standardized system used in many industries to easily identify the type of fluid transported through a pipe. The use of color for identification helps ensure safety and proper handling by minimizing confusion over different types of fluids.

Steam systems often operate under high temperatures and pressures, making it crucial for personnel to recognize steam piping quickly to prevent accidents or malfunctions. By using white for steam, maintenance and operations personnel can instantly understand the potential hazards associated with the piping.

While other colors in piping systems denote different materials, in this instance, white consistently represents steam, emphasizing the importance of color coding in operational safety.
