I would like to fit my dumplin valves to my (Smithy)stainless steel hard-pipes.But the T off supplied is alloy,there is also a pair in mild steel they have a recessed groove to eccept the bov securing grub screws.Can these materials be welded to s/steel.Pipe sizes are 51mm hardpipes t'd off to 34mm.If any Peeps can help I'd be gratefull.I would even consider a red silicone T if I could find out where from,I've search the Web.Standing by ...Vinz...

The mild steel T pieces will weld to stainless no problem. Make sure you give it to someone who knows how to weld though and not some back street rough arse with a mig set who will probably blow your hard pipes into oblivion.
