Boiler tube installer or expander?

[Butch(OH)]

Years ago I watched a boiler repair man install some tubes in a heat exchanger. The tubes were copper and a slip fit in the bulk heads. He had a tool that had three rollers and a tapered punch like center part that he used to expand the tubes until tight and then he turned it with a wrench. Anyone know what they are called and where a person could purchase one? No, I am not working on a boiler, LOL.

They are called tube rollers, common in the marine industry. Try a search on boiler or marine supplies.

A few years ago I had several bad copper tubes replaced in an industrial chiller. The repairman used a tool made by Ridgid to expand the ends of the copper tubes into the tube sheet.

Butch I have some of these tube rollers/expanders. I don't know what sizes they are. Can check tomorrow. What size are you looking for? Gary

I don't know how they are ID'd as to size but the smallest one I have looks like it expand to about 13/16. It is not in a box and only has one set of rollers. The other larger ones I have are in wooden boxes are new and have two sets of rollers with them and the rang of expansion is on the box.
