Hello,
I have a question regarding the methodology for using line loads for calculating stresses in lifting lugs in the head of vertical pressure vessels. We recently have compared our methodology to EN-13445-3 (via COMPRESS). We found that the equivalent calculation diameter from EN-13445-3...
Just looking for some opinions from the community,
Specifically lift lugs with repads, but also repads in general:
- MechE #1 has rule of thumb “repads should not be thicker than shell/head they are attached to. This is to avoid local stiff areas and stress risers”
- MechE #2 says it doesn’t...
