Design Radiography and Joint Efficiency

How to design radiography and determine joint efficiencies in pressure vessels refer to ASME Section VIII Division 1?
Outline video
- Design of Radiography (Full, Spot, None)
- Marking of Radiography (RT 1, RT 2, RT 3, RT 4)
- 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

Semangat terus pa 💪 di balik kerjaan yang numpuk tetep bikin vidio 💪

[@fnengineering]

Hatur nuhun sudah menonton dan berkunjung

[@MrSachin107]

Thanks

[@anengineer8647]

Who will decide which RT class applicable for job.. mechanical designers or process designers?

[@fnengineering]

It should be a mechanical designer

[@surry99]

Can you do a video showing how to calculate the size of weld required to connect a nozzle to a shell?

[@fnengineering]

Hello @surry99 thank you for watching my video. Regarding your question, I have explained in the previous video "Nozzle Reinforcements Design of Pressure Vessels (Part 2 or Part 3)". You can go to this link kzbin.info/www/bejne/gIfJdJ2bjZlqmK8 or kzbin.info/www/bejne/mH_PgperhLVlo6s. Is it enough for answer your question?

[@surry99]

Thank you...I missed that one.

Izin bertanya Jika ada sebuah pressure vessel terbuat dari seamless Elipsoidal Head akan disambung ke Seamless Shell, vessel ini akan dilakukan RT-3 / Spot Radiography as per UW-11(b). Pertanyaannya berapa kah nilai E untuk Head dan nilai E untuk Shell itu sendiri. terima kasih 🙏🏼

[@sdf4446]

Why background music.

[@shreyashmehta839]

Can you teach me how can I calculate the cost of full and spot radiography?

[@fnengineering]

Do you mean cost of radiography? It depends on length, number of radiography, and visit

[@shreyashmehta839]

@@fnengineering Yes. Exactly. Is there any specific formula or a method to calculate?

[@fnengineering]

@@shreyashmehta839 yes, there is certain formula to calculate that
