Guys, what are the the Standard Upstream Oil and Gas Piping Colour Schemes in PI ProcessBook, for example:
- Full Well Stream (FWS) Piping - Is it Green?
- Gas Piping - Is it Red?
- Water Piping - Is it Blue?
- Compressed Air Piping - Is it White?
- Chemical Injection Piping - ?
- Diesel Piping - ?
The Piping connections in the DCS Screens are usually all white.
Is there an International Piping Color Code or Scheme that I can refer to.
