Thread Content
Hello everyone. Regarding the basic colors and identification colors for pipes, what are the basic colors and identification colors for media such as process water, circulating water, emulsion, vacuum, wastewater, deionized water, soft water, and hot water? The standards list only the colors of common media such as air, the base color light gray B03, and the identification color bright red R03. For water, the base color is vivid green G03, and the identification color is white. With so many different types of water, how can these colors be distinguished? What color is the rest?
These are the main color codes used domestically; for more detailed classifications, one can refer to international project management standards or those used abroad
Are there any foreign standard names and standard numbers?
