Boiler Wall Thickness

Hello,
I purchased a Keystoker Boiler and I wanted to find out if anyone knows how thick the inside boiler walls should be? I am testing the wall thickness with a ultrasonic thickness tester. I am getting reading from 0.144" to .204" Would this be normal? I am not sure how thick the walls were when it was new. The boiler was manufactured in 1987

Thanks,
Paul

A call to Keystoker would answer the question fairly accurately.

I have a little experience with those testers, unless I had used a junk one the thousandth place is just a number hanging there. 10 gauge is about .140" and is fairly common, when steel plate is rolled into a cylinder its thickness changes so keep that in mind.

I received this response from Keystoker

The boiler steel started out at .25. The only time our boilers are taken out of service are if the home can no longer do the coal and ashes or if the boiler will not hold water (it is actually leaking and can't be welded).

If the boiler looks fine it probably is...pressure test it and call it a day.
