Hi everyone,
Could anyone explain how to resolve the below presssure vessel design analysis error?
"Computed overall MDMT was higher than required value"
Thanks.

RE: Pressure Vessel Design
A higher computed MDMT means that you have specified a lower MDMT input in your design. You would have to read more on UG-20 and UCS 66 to fully understand this topic. Depending on the situation, you can get away with lower MDMT by doing PWHT, Impact testing, etc. Figure UCS-66.2 provides rules for determining the lowest MDMT permissible without impact testing.
