Can I Swage Gas Pipe?

The hand held expanders are terrible things. They split the side wall of the pipe immediately. They are too aggressive.

You have to anneal the copper first before using them.
If you use coiled copper and cut the tube with pipe cutters, you have to remove the burr completely.
We used to use them all the time - not so much anymore due to pressfit fittings.

Saying that we did a 65mm gas main recently and decided to solder the joints due to cost of fittings.
We even pulled out the branch pullers for tees and the expanders for swaging.

Theres nobody more old school / old git than me lol
Just never heard it .

You must remember the old swageing tools had to knock them in with a hammer, but copper pipe back then was a lot better quality
