Dear all,
I am working as the client engineering lead for a new plant. We are completing the FEP or FEED (front end package) shortly. I am checking RV calculations as client.
On one case I found that the tube rupture case was not calculated becuase each side has the same MAWP.. I trust the EPC involved but they only stated references (ie it is in this code) as a reason. I want to understand why you dont calculate it for this case..
is it to do with if the Heat exchanger has differnt MAWP's the tubes can rupture due to differential pressure stress ? and this is common (or common enough to require a RV to prevent overpressure from this event ?)
