I had a bit of time on my hands today (don't ask!) and I was wondering how long it would take for my old gas pipe to rust and cause a leak ?
It is hard to see in my pictures as it is in the background.
I am not even sure if there is gas in the pipe anymore although I think there is as why else would the pipe be turned off and capped ?
The pipe was there when I moved into my house 25 years ago (I just paid off my mortgage 3 months ago)
I googled it and apparently old gas pipes were made of carbon steel that does rust although modern gas pipes are made of polyethylene (PE)
Am I worrying over nothing as the gas pipe is embedded in concrete which would surely 'eat' into the carbon steel in the same way that it does to copper piping?
My water mains is made of copper and that runs under the foundation of my house and it doesn't have a protective sleeve to protect it but that's another story !
