Boiler tube standards equivalence
Boiler tube standards equivalence
(OP)
A friend of mine is building a boiler for a model steam engine and is having trouble sourcing the appropriate tubing.
I am pretty sure this is a question that gets asked regularly. A quick search of the previous posts does not seem to give an answer however.
He has bought a piece of seamless tube which has certification and at face value would seem okay but the local certifying body is having trouble (don't want to , or don't know how to ) working out whether it is equivalent or not.
One attachment is the "certificate" that came with the tube . To me it looks like its EN 10305-1. The other attachment is the standards required and there are a few ASTM A106, ASTM A53, BS3601, BS3059 Part 2.
I would suggest that these standards are not directly compatible

My friend is not in the USA but some distance away in Australia and he is building from a UK design and i think this is where the problems start because of some of the castings he is importing for the project. I have not seen any of this but this is what he has explained to me as the problem.
The castings require a 6” OD x 5 Gauge, or .212” Wall Thickness seamless tube but the ASTM standards listed above only cover a 168.9mm seamless tube.
Hence the search for an equivalent standard. As i understand it the tube he has purchased complies with the EN 10305-1 standard but the the Model Boiler Code references the ASTM standard.
Ultimately the question is whether or not the piece of tube which meets the EN 10305-1 standard also meets the other standards that i listed above.
