Nicked a gas pipe

[Justin Passing]

I once saw a copper patch soldered to a gas pipe, possibly to repair something similar.
Could that be done to get the op peace of mind?
Or is it some sort of bodge?

Technically No, that's not an approved gas fitting.
MOst things like that are covered more or less well by "normative documents", like anything regulated really. Same way that you can't hammer a gas pipe closed and weld or braze or solder it up, it's not an approved procedure.
That one would be a British Standard or maybe its EU replacement.

A better bodge/easyfix, in that nobody would find it, would be to cut the pipe and use two soldered slip-couplings; one to go over where the damage is and one to rejoin the pipe.

The downside of replacing the "polished" bit is that you'll then need two couplers - one at each end of the replacement section of pipe. This will mean 4 new pipe joints, and such joints have a greater risk of leakage than plain pipe. Unless your "nick" is really deep I'd be tempted to leave it.

If a person would feel better by doing something, what would be wrong with a perfectly applied blob of solder from a soldering iron, then forget all about it?
