What is the standard color of pipe used for water?
Blue
Blue marks are for potable/drinking water. Water pipes usually have valves accessible on the ground surface along their main routes and service lines. Other colors such as purple and pink are sometimes used for unknown/unidentified underground utilities.

Why colour coding of pipelines are needed?
Identification and colour coding for the pipelines is essential to avoid potential hazards, accidents. Giving a colour code and maintaining the uniformity for colour coding in industrial piping will eliminate accidental chances, reduces operational errors. Moreover it enhances the safety aspects.
What is colour band in piping?
Colour Coding to Pipelines (Ground Colour and Colour Bands) Giving a base or ground colour to pipelines based on fluid flowing, the line identification is done. Further colour bands are provided accordingly. The base/ground colour gives the basic nature of the flowing fluid (i.e. water, air, gases etc.).
Why are pipelines color coded?
The ANSI/ASME color codes for pipes also leave several color combinations for “user defined” pipes. This is important because it allows facilities to plan out certain pipes that don’t fit in with the normal standards.
What is pipe code?
Piping codes defines the requirements of design, fabrication, use of materials, tests and inspection of pipes and piping systems – what you need to do. A code has a limited jurisdiction defined by the code. A code is not law, but can be adopted into law.
