So would these pipe expanders be effective in a copper boiler with small tubes say, 3/8"? You would be able to expand the tubes, sure, but I don't think the copper tubeplates will resist the expansion well. They may just stretch and buckle. The copper tubeplates will also not likely be stiff enough to resist steam pressure with only expanded copper tubes to hold them. If you are fitting copper to copper, why not silver solder the tubes in? If things are chemically clean at the joints and you have enough heat and flux, soldering tubes is not difficult. I'd be much more comfortable with soldered tubes in an all copper boiler. So will your boiler inspector. JD |

I was trying to pull your leg Duncan, not challenging your earlier post. 'Not necessarily a good thing though!" was emboldened and underlined when I turned it into a link. Now it's too late to fix it I see it also gave the phrase an unintended sharpness. My ponderous attempts at humour would be more obvious if I learnt to use emoji. Unfortunately I can't - it would disappoint all the people who know I'm old-fashioned! Apologies again, Dave |
