Radiography marking as per ASME Sec. VIII Div. 1

[Manoj Mumbai]

Dears,

Vessel joint efficiency is 0.85

Vessel RT requirement is Spot. 

Dished end having weld seam and fully RTd as the joint efficiency of head is 1 and other parts satisfied as per UW-52 spot RT requirements. So what would be the marking on name plate, RT3 or RT 4 or RT2.

Thanks in advance.

Manoj

Dear manoj 

       When some part of the vessel undergoes full RT and other part undergoes spot RT satisfying the requirements of UW-11 Asme sec VIII div.1 & where none of the other markings RT1, RT2 & RT3 is applicable then as per UG-116 vessel shall be marked as  "RT4".
