Capping steel gas pipe buried in concrete

[tamz]

How on earth will you thread onto a buried pipe. Probably easier to cut grind and weld a plate on. But that's just stupid if you can get to a tee and thread in a plug.

You need to dig enough out to get a power head on but your average Joe plumber won't have one so best to cut it with a recip unscrew the cut and plug

That's a big hole in a concrete floor. Pipe 40mm down, the the cutter add on another 125mm so u can get in square. Loads of fun.

Thanks guys for all the comments.

I managed to dig out enough concrete for the gas guy to be able to cut the steel pipe with a reciprocating saw. He then put a blowtorch onto the screw joint at a T junction and much to my surprise he was able to twist out the pipe.

He then capped off the T joint and tested the system for leaks - there were none. He then put in a new section of brass pipe from the T joint, partially below the concrete. He wrapped that in tape.

So, for a job I thought could be a nightmare, it went quite smoothly.

Generally the pipe looked in reasonable shape, but as it moved from the T junction it became quite corroded. I think it's no surprise since the concrete wasn't as dense in one part of the floor and we've had a washing machine and dishwasher in that spot with various spills and thrills.

Anyway, one month from getting the gas cut off, we're warm again.

Thanks guys.
