Applying ASME Boiler Code to Steam Generation

2013-1-1 · (Page 1) The main focus of the ASME boiler code is on power boilers, rather than on petroleum refinery or petrochemical heaters, so definitions are sometimes not clear. Furthermore, it can be difficult to define which authority has jurisdiction over steam generation systems in the CPI. Even in the U.S. This article provides guidance on the requirements for stamping within the ASME code and
