[Dsg-rich] List of Design Authority for Pressure Systems

[Patrizia Rossi]

Tim,

I checked the list of the Jlab design authorities and Joseph Matalevich is there. So, why are not you satisfied?


thanks

If it meets certain minimum requirements (stored energy, pressure, fluid etc) certain actions must be taken. Relief calculations are just one of the requirements. Assigning a Design Authority another. Depending on the characteristics of the system, a Pressure System number may need to be defined as well as the accompanying documentation. The Design Engineer can make this call.
