Very informative post there Mike, I already knew some of it because pipe is very simular.
We called our rings a "backing ring", only used on critical lines carrying very high pressure steam and such. Our pipe always had a "J" bevel to carry many weld passes, preheated and brought down slowly sometimes 2 days on the bigger stuff. Our rings had pins that allowed the ring to be pulled up tight and also set the gap, then got broke off on the first pass. Fascinating stuff, never got to work with much track welding, but man it makes a pretty weld when set up right!
Do you know what pressure they failed at?
