I have an electric pipe freezing kit and I need to freeze 3 barrel pipes 1 is the mains which is 3/4 inch,1 is 2" which is the hot,1 is 1"1/2 which is the cold. They all drop down from the ceiling into the room and all have elbows on I need to attach iron to copper fittings into each of these pipes and I was thinking would the best way to do this be by freezing the pipework? And unscrewing the barrel pipe from the elbow fitting allowing me to screw on my iron to copper fitting? I'm a bit nervous doing this as I've never frozen barrel pipe. This work is being carried out in a school. Any advice on pipe freezing guys??????????

Unless you have plenty of CO2 I would be very nervous of freezing a 2" pipe, BOC operate a speciallist pipe freezing service they turn up with a lorry full of CO2 and carry out the freeze for you the smaller pipes should not cause too much problem as long as you have the correct sized bags for your freezer!

Why would he need lots if co2 for an electric freezer.
We have a rofrost turbo2,do loads of big barrel but ding anything above inch takes a while to freeze.the heads have to be showing below-15 to ensure it's a sound freeze.
Don't leave on too long,I've split a 2inch pipe through over freezing.

2 " hot in a public building
I had a 6" heating pipe in a building frozen by specialist contractors.

it stayed frozen. I was a mere by-stander but I made sure my by-standing was done at a suitable distance. DIYnot Local
