Piping Color Code
Piping Color Code
(OP)
Is there any color standard for power plant piping (i.e. Lube Oil, Fuel Oil, Raw Water, Condensate, etc.)? We are trying to implement a coding system at our plant and cannot seem to find any standard.





RE: Piping Color Code
There are ASTM colors for different material but there's no industry or code standard service specific color scheme that I'm aware of.
The most consistent color I've see used at different facilities is red for fire fighting systems. I've seen nitrogen lines painted blue one place and green in another. One facility painted lines yellow if they contained H2S bearing streams...

Don't get me wrong, I'm a fan of labeling and hazard identification but I think powerplantop is hunting different game.
Maybe not.

Colour-coding can be a problem for the colour-blind if the lines are not also properly labelled regarding transmitted fluid and flow direction.
Personal, off-topic anecdote: My transition to CAD was especially difficult due to having to visually interpret something other than shades of gray when "drawing". Thin yellow, green and red lines on a monitor all look the same to me.

Googling 29 CRF1910.144 provided some insight into Big Inch’s position. Its title is Safety Color Code for Marking Physical Hazards. At least that’s what came up in OSHA’s site. 1910.144(a)(1) – Red shall be the basic color for the identification of: 1910.144(a)(1)(i) – fire protection equipment and apparatus. 1910.144(a)(1)(ii) – Danger. Safety cans or other portable containers of flammable liquids having a flash point at or below 80 deg. F, ….1910.144(a)(1)(iii) – Stop. Emergency stop bars on hazardous machines such as rubber mills, wire blocks……1910.144(a)(2) – [Reserved]… 1910.144(a)(3) – Yellow. Yellow shall be the basic color for designating caution and for marking physical hazards such as: Striking against, stumbling, falling, tripping, and “caught in between.” I’ll let ya’ll do what you want with that information.
Anyway, powerplantop I commend you on your cause. Good line identification by whatever means can make life better, and safer, for everyone. Vast expanses of piping would most probably be better addressed by strategically placed labels (w/flow direction). I suppose if the resources are available, localized systems can probably be addressed by paint: stuff like equipment lube and cooling systems that doesn’t usually have to be chased too far. I’ll be an effort to get everything clean enough to paint. If you do proceed with mass painting, make sure the right paint system is use for the temperature and material of pipe.
Back to labels, you shouldn’t have any trouble finding useful products. Some things to think about: 1) accuracy – the wrong label or direction can put someone in a world of hurt, 2) terminology – not tough with “utility” type services but can get sticky when you get into process streams that can be called different things by different people, 3) locations – obviously you want identifier where people can see them; I favor valves, above/below ground transitions, in/out of pipe rack transitions, and equipment ins and outs.
