Getting the over size plug made, would be my first option. Bobs right on this one.
Second would be to try and expand a reducing bushing. You can still get it out.
Remember anything left out side the tube sheet can be cut off.
Another option is to put in a plug with a drilled hole through the center and drive in a tapered plug into it, expanding the threaded plug. Any thing to not make the hole larger.
If you decide to use just a tapered plug, you will need a clean reamed round hole. I’ve used these plugs up to a 1000-PSI hydro. I make my own but you can buy them.
There are a few more options but they require some machining and skill on making up the parts.
Before you weld look at the Elliott tube plugs.
Also they make tube rollers as well. I use the Wilson but I’m sure they’re just as good.
Measure the inside diameter of your tube and talk to a sales rep. They work over a small range in diameter.
