 concrete - black iron gas pipe
Author: cocoloco (IL)

does concrete eat up black iron pipe?

meter at side of house, the gas line comes thru concrete foundation without a sleeve, been that way for 60+ years... im sure im not the only one with this setup.

Should i be concerned about this?

Unfortunetly a visual inspection is only possible if i tear up a wall or remove siding to get my eyes on it.

it probably not a big job to change the pipe but enlarging the hole and sleeving it is probably more work..

thx for the info, btw i just pulled the siding back around the pipe and it appears to go thru the sill plate on top of the poured foundation.. so its not embedded in concrete

from the internet

Black iron pipes are made of a low-grade mild steel compound,

What steel are rebars made from?
Rebar - Wikipedia
carbon steel

did you ever try to cut a re bar with a hacksaw ?
