I am making headers for a ‘pressure vessel’ out of pipe and crosses. It will be 4” sch. 40 steel pipe with two (2) 4” butt weld crosses. I would like to have these cut in half after being welded up and be able to use BOTH halfs. It will need to have a small kerf as I can’t have much material lost during the process. Maybe around 1/8” max?
This would all be done as opposed to using just butt weld tees, cutting in half and then scrapping half the pipe and tee. This would also cut down on the number of welds (which will need to be x-rayed also).
My question is what processes of cutting would work for these headers? EDM, laser, plasma, saw, torch? I’m not real familiar with what’s available and just would like some input and what would be the most suitable for this application.
Thanks for any input
