Gas Pipe Protection in Foundation Wall

I have run into a lot of unprotected gas pipes which are in contact with the masonry walls. Does any know when this has been enforced? :slight_smile:

Pete, can you be more specific? What kind of gas piping, and what type of masonry? True masonry, or brick veneer? Yes, makes a difference. Thx.

natural gas
concrete block

Black Iron?

I will assume Black Iron through Block… no protection required by my AHJ. Typically, penetration hole has a butt load of sealant. Very rarely see any rust or damage. I do not call this application out as a defect.
