Design Radiography and Joint Efficiency

How to design radiography and determine joint efficiencies in pressure vessels refer to ASME Section VIII Division 1?

Study case of radiography and joint efficiency

Design Radiography
1. Full radiography
Reference: UW-11(a)
Requirement: Lethal service, Steam exceeding 350 kPa, welded thickness exceeds 38 mm, welded thickness exceed of list material, specific material as per UHT, ULW, and ULT, using electro gas or electro slag, user requirement

2. Spot Radiography
Reference: UW-11(b)

3. No Radiography
Reference: UW-11 (c)

Marking Radiography
Reference: UG-116
Type of marking RT 1, RT 2, RT 3 RT 4
RT 1, vessel satisfies the full radiography requirements of UW-11(a)
RT 2, vessel satisfies the full radiography requirements of UW-11(a) and apply spot radiography requirements of UW-11(a)(5)(-b)
RT 3, vessel satisfies the spot radiography requirements of UW-11(b)
RT 4, part of vessel has satisfied the radiography requirements of UW-11(a) or none of the markings RT 1, RT 2, or RT 3 are applicable

Study case
Define joint category
Define joint type
Define joint efficiency
