Steel Gas Piping

Steel Gas Piping

Steel Gas Piping

(OP)
I read in a code but do not remember where but when two or more black steel pipes are installed at the same location, the gas pipe is required to be identified with yellow stripping or painted yellow.

Does anyone know where this may have come from? I am in Texas, and I have looked in the 2021 IFGC and the NFPA Gas Code but did not see this verbiage. I know I read this, and it does make sense if you have sprinkler pipe and gas pipe installed next to each other, the gas would require to be labeled.

RE: Steel Gas Piping

vague information provided . . . gas pressure, location, etc. from what you wrote, it appears this gas pipe is a service line. upstream or downstream from gas meter?

Perhaps this link will aid you.

RE: Steel Gas Piping

Think it's just a good idea so you don't cut into the wrong pipe.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: Steel Gas Piping

(OP)
The 4” gas line is upstream from the meter and is installed overhead for a cooling tower.
The code that I read did state the reason is so someone doesn’t mistaken it for something else. I just do not remember where this was called out

RE: Steel Gas Piping

Pipe color codes

ANSI/ASME A13.1

ISO 14726

RE: Steel Gas Piping

I have seen client specs that mandate piping identification schemes.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
