Hi Dave,
You asked: I'd be interested to know exactly what your schedule of inspection is for a boiler. In my head I have an idea of what I'd do - it would be interesting to compare
Well it is not easy to replicate the whole of the guidelines, you could get hold of a copy of them from the Southern Federation, or the Northern Association.
There is a different emphasis between the way that the professionals working for an insurance company approach it and the way we approach it, as far as I can see.
An example might illustrate this. One of our members has a model showman's engine with a steel boiler. He invited the insurance company's inspector to come and give it the once over. The inspector after some very thorough inspection detected some stays that had waisted to quite a small diameter and as a result he failed the boiler. I am sure that if a club inspector had inspected this boiler and assuming it passed its annual hydraulic pressure test the boiler would still be in use. The club inspector does not have the advantage of fancy test equipment like ultra-sonic thickness measuring equipment.
The club testers rely much more on the results of the pressure tests than the professionals do. The club testers require an annual hydraulic test, which I understand the professionals do not.
I don't suppose this answers all your questions - in fact I doubt that I could answer all of the questions.
Cheers,
Roger Mason
