Discuss Can I Swage Gas Pipe? in the Plumbing Jobs | The Job-board area at PlumbersForums.net
I think 15mm is 0.7, and 0.9 for 22mm, so a bit thinner than your stuff. I'd be tempted to do it on water (it looks good), but only if I could get a squeeze-operated expander. Seen one in books, but not for sale. Can't be bothered to have to start hitting an expander with a hammer while supporting the pipe somewhow.Just out of interest - off topic.
What are your copper tube wall thicknesses?
We measure our pipe OD.
1/2" - 0.91 mm
3/4" - 1.02 mm
1" - 1.22 mm
The hand held expanders are terrible things. They split the side wall of the pipe immediately. They are too aggressive.
You must remember the old swageing tools had to knock them in with a hammer, but copper pipe back then was a lot better qualityTheres nobody more old school / old git than me lol
Just never heard it .
