Hi, I'm a naval architect and just comparing to the boilers on a steamship. Question: What your doing with that air powered tool is expanding the ends of each boiler tube? Will doing that make it water tight? When rebuilding a locomotive and you do a hydro test, is the outer part of the riveted body/tank generally sound or can they suffer metal/age fatigue? A steamship's boilers are inspected annually by a certified expert. To operate a steam locomotive are the requirements the same? Thanks

@henrynevins Correct, each end is expanded into the tube plate and the fire box end is seal welded. Yes the boiler is hydro tested to 1 - 1/2 above its working pressure. Generally the tube plates and inner firebox around the stays suffer a bit of fatigue, part of the rebuilding process is Non Destructive crack testing as

@henrynevins well as X-raying of any repair work carried out by certified technicians. Our boilers are subject to an annual inspection, usually a visual followed by a live steam test as well as a check of maintenance logs etc, also carried out by a certified person, he is also involved through various stages the rebuilding a boiler. hope that answers some of your questions. Cheers.

Thanks for the detailed instructions on the rolling of the tubes.

Is that an impact wrench you're using Alastair ?? Shame on you if it is.

@SteamIncorporated Thanks for the insight and information. The liner SS United States on its maiden voyage in 1952 set a world speed record. To date, though idle setting in Philadelphia for many years, she still holds the record and did it on steam power. If she was to ever run again there aren't many engineers these days who are savvy with steam and boilers. Happy to see you keeping this best, old and time tested technology alive.
