Are all pipes in a home the same size?
I found some 'fire proof cloth' at Lowes by my house when I needed to do the same thing. It was a little hard to find, but it sould be available at Lowes/Home Depot or your local plumbing supply house. It came in about 1 foot square that I staple-gunned to the stud to protect it while I was using the butane torch. Worked like a charm.
Been there, done that. Get a cookie sheet, and put it behind the pipes. Then use your torch. There is also a gel on the market that you can use. It's specially designed for this type of application. You spray it on, behind your weld, and nothing burns. When you're finished, simply wipe it off.
hello, I like the cookie sheet idea, or a bigger sheet of tin, I would also wrap the pipes with very wet rags on either side. Make sure you have a charged fire extinguisher near by, just in case, and do not leave the house for a couple of house later. Fire is sneaky and not forgiving.
No. There is no fit all one pipe size. Also since many builders do not follow regulations, building materials vary drastically.
1/2 to 3/4.normal sized house.1/2 will do it.good luck.
