The pressure vessel is equipped with a safety valve port, but the equipment manufacturer says that this port should be converted into a spare port Because if a safety valve is specified, it becomes difficult for them to get approval (since the medium is a mixed one). But I think that if a spare port is specified when what is actually installed is a safety valve, isn’t that considered irregular operation?
Sign and confirm; otherwise, any unauthorized change in the intended use is not allowed. Responsibilities must be clearly defined to avoid disputes!
Prepare the relevant design documents based on the actual situation (with signatures)； Also, why is it difficult to get approval for safety valves designed for mixed media? In actual installations, mixed media involve more components than single-media systems
When specifying a safety valve port, it seems that a safety valve calculation sheet must be provided. If it’s not written, **then it won’t be taken into account.**
