Universal Color for HVAC High Pressure System

08/27/2009 1:51 PM

I need to know what color is used to identify a high pressure HVAC system. I mean, there are color-coding for almost anything, like green for safety, red for danger and emergency, yellow for caution, etc.

What do you mean by "high pressure" as applied to HVAC systems? You are referring to heating, ventilating and air conditioning right??

Yes, I am referring to heating, ventilating and air-conditioning. I am not familiar with this topic and I've tried to google it but can't find the answer I need. You see, I am referring to the piping system. How will I be able to identify the pipes/ high pressure from other piping system, is there color-coding for HVAC system? thanks.

What kind of piping? Refrigerant, chilled water, condenser water, hot water/steam? Refrigerant piping can be high pressure, but unless you are pumping extremely long distances or heights, chilled water is not usually very high pressure. Refrigerant, chilled water and hot water piping will typically be insulated, and should be identified on the outside of the insulation with system labels and flow direction arrows per code requirements. I don't recall that there are color requirements for these labels, but you might check your local codes to see if there may be some specific requirements.

thank you, I think we're getting there, what I need to know is if there is universal color coding for refrigerant, condenser water, hot water/steam, etc. If there is, I want to know.

No there is not a universal one. There are some companies that have made up their own codes for clarity. But as far as I know there is not a universal color code for HVAC sytems.

Hope this helps

Check with Seton or Brady for pipe label information. http://www.bradyid.com/ There is an ANSI standard some facilities follow for color, size, and location of markers; other facilities have their own custom color coding and markings. There are also NFPA standards for medical gas pipe markings.

We use a standardized "master specification" library as the basis from which to create bidding documents all commercial construction projects.

In the HVAC Piping Identification Section (230553) we reference the ASME A13.1 - Scheme for the Identification of Piping Systems. The newest one (2007) is available here: http://catalog.asme.org/Codes/PrintBook/A131_2007_Scheme.cfm

We also typically use the products from "Seton" as our 'design base' for product equals, and they follow this color, size, and identification scheme for the basics you mention.

Whenever a piping system has zones, multiple branches, or loops that need to be further identified, we will create what we hope is a simple color-banding schedule and have that posted in the central mechanical room, and require that banding to be used on each side of each wall/floor/ceiling penetration.
