Does the NEC specifically require metal gas piping to be bonded?

If you are talking about CSST piping ( the yellow stuff ) then no however the manufacturers of those products do require bonding.

Here in the Colorful State, we allow the second sentence from the end of the quote to do the bonding.
Actually all states should if they are following the NEC as it's worded.

Dennis, why did you assume the OP was talking about CSST?

I am not really assuming it is but it could be what the op is asking since that is a common question. Many people are very confused on the issue.

But the OP's words were,

which is specifically addressed in 250.104(B)

Does it really matter. CSST is also a metal gas pipe. I was just making sure the op understood there was a difference but it seems you are not happy with that so......you win-- I won't bring it up

I don't know what your problem is Dennis, go back and read the thread in order reading the words of the posts and not what you want the posts to say.

In post #6 you asked me if I assumed it was black iron pipe and in turn I asked you why you assumed it was CSST, then I pointed out the OP's wording and why 250.104(B) would apply, sorry if you think that was an indication that I was unhappy (I'm not) and sorry that it obviously upset you. :rolleyes:

So if I am reading this right as long as the gas pipe is bonded at entry then the flexible yellow gas line is bonded also, but nothing after the yellow flexible line is. such as in larry question in the other post
I'm glad someone understands what my question really was. :)
