RE: Elliptical head
1. Mechanical design (strength calculation) : If it is applicable to ASME Sec.VIII (or any other pressure vessel code), the required thickness of shell section (including the weld joint of 2:1 ellip. head to shell) shall be strength-calculated with the joint efficiency per the applied RT Level (none, spot, or full).
2. Mechanical design (metallurgy requirements) : The weld joint shall be designed/examined with RT (or other NDE) according to the requirements for service. e.g., 100% RT for cryogenic service and/or environment cracking service.
