Mandatory appendix 28 show us alternative corner joint details for box headers for air cooled heat exchangers.
For lethal service categorie B and C welds shall be butt joint type (UW-2(a)(1)(b)) and has to be fully radiographed (UW-2(a))

Could appendix 28 also be applied for lethal service application?

Thanks for your feedback,

Why do you post a question in two sections. See in Sect.VIII Div.1 forum. The answer is NO.
