colour codes for tubing

[dirvana]

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.?

try asking the local village/ city/ town if they have a required building code. use that.
