Are calculations to latest version of the ASME BPVC code required for replacement PVs?
Are calculations to latest version of the ASME BPVC code required for replacement PVs?
(OP)
Our company manufactures multipoint thermocouple assemblies that are designed to the current ASME BPVC SEC.VIII, DIV.1. Frequently we get orders for replacement assemblies, with no changes, and I get requests for updated calculations based on the latest release of the BPVC. I thought I read somewhere in VIII, DIV.1, that a design could be accepted based on proven service of the same design with no additional calculations required. I looked through the 2015 version, and could not find any such justification.
Perhaps I am just thinking of wording from other section of the code, such as piping. Are calculations to the latest version required for these instances?
