Pipeline color coding:

The pipelines in plants or industries carry harmless or hazardous contents. So it is most important to identify them. The proper color may be applied to the entire length of the pipe or in bands of 20-25 centimeters wide near the valves, pumps, and at repeated intervals along the line. Anti-resistant colors should be used where acids and other chemicals may affect the paints. The entire length or a portion, more than 30 cm, of a pipeline should be painted so that it should not be mistaken for a color band. For longer pipes, the interval may be 50m.
