April 27, 20197 yr @Nickfromwales @PeterW I've quite a bit of 28mm to do on a forthcoming job and wondered if you have any thoughts on bending machines other than the bog-standard floorstanders? Specifically handheld/ portable. I'm thinking of the crossbow-style ratchet or hydraulic ones in particular, but keep reading that the ratchet ones are only suitable for soft copper and would wrinkle half-hard. No, can't use Hep before you say, it has to be good for steam service, and we're pretty much limited to compression fittings. As we're only going to be looking at 30-45deg bends for offsets and such rather than pulling 90s, is one of the above units worth the try?
April 28, 20197 yr Motorised machine with guides that stretch the pipe would be my choice, probably best to hire one. Get everything laid in as far as you can to shorten the window for hire.
