colour codes for tubing
(OP)
Dear all, we have to extend the heating (pipes and tubes)in an installation in a clinic, where can we find the code about how the pipes and tubes sould be coloured in order to recognize them. An exemple:
- Natural gas = yellow
- Waste water = black
- Water to and from cooling tower = green.
How about water with anti-freeze, oil, demineralised water, etc.?
