Hi chaps I am trying to recommissione a 3.5 gauge columbia.as many of you will know its a large engine and I don, t really wish to remove the boiler if I don't need to.the thing is that as far as boiler history goes all I have is the original bill of sale from swindon boilers.along with the bill of sale I also have acopy of swindon boilers first hydhydrostatic boiler test at 2x working pressure. This is dated 1997.this leads me onto my question, will a boiler inspector want the boiler out for inspection (a lot of work ) or will the boiler justneed testing at 1.5 x working pressure. Michael

Talk to your boiler inspector: See what they required.
The ticket is well out of date so be prepared for a full strip down.

The advice is that a boiler should be examined unclothed at around ten yearly intervals at the boiler inspector's discretion. Most will be relaxed about this if there are no signs of leakage from under the cladding and no signs of movement on visible surfaces. Ten years fits well with the four yearly hydraulic test intervals as you can see. If the boiler hasn't been steamed then my fancy would be that you would just need the routine hydraulic and steam test, but if it has been used then expect the inspector to want the cladding off. Unless it shows signs of having had repairs then 1.5 x wp with the fittings on will probably be acceptable, otherwise a full 2 x test.
If this is a wide firebox with nothing hidden between the frames then you might get away with removing the cladding and leaving the boiler on the frames.
Talk to your inspectors before you do anything.
