Thanks for clarifying. I've been in touch with the inspection agency and they too are looking into it also. I wanted to do my own research to get a better handle on this problem.
Thanks. I am new on the scene and don't have boiler experience. Our existing boiler is new, running off and on for 3-4 months. We've had problems with the tubes leaking at the steam drum, vendor re-seated and hydro tested, still leaks badly. They are going to weld all tubes starting next...
Per ASME code, at what pressure do the tubes have to be welded connections? I don't have a copy of the code available. I am trying to understand why there is a discrepency with a vendor.
Thanks.
