The internationally accepted guidelines for pipe marking are based on 4 main areas of concern: the format of the standard being used, the color of the pipe application (water, gas, or other liquids) as well as the height of the text required, which is based on the size of the pipe, as well as the surrounding environment or infrastructure where the pipes have been installed.
The guidelines seen here in the guide are internationally recognized and will help you towards compliance. Еще
