NDT Requirements for Super Duplex
NDT Requirements for Super Duplex
(OP)
Where do I find the specific code for NDT, Radiography of 12" Schedule 80 butt welded super duplex? The pressure rating is up to 1000 psi and the fluid is filtered seawater.
B31.3 sends me round in circles.
The initial seemed pipework was 100% radiographed, there is now a requirement for butt welding.
We have assumed 10% off site examination and random radiography of the erected in situ welding, amounting to 50%.

What is the code of construction for this project? Once you find out, go to the Inspection section of the Code, and you will find your answer. Base material does not govern NDT requirements, it is normally pressure and service temperature. If you have NO code of construction, you are on your own to establish requirements.

This is also why I included detail as to the material and the fluid being moved.
The pressure rating although up to 100 psi is contained within the ASME B16.5 Class 2500 flange rating so I am considering this as "not high pressure" and the fluid is not toxic therefore it is in the normal category.
I read this then as either no examination, only visual or at the most Random RT.
Please advise

catagorised as "normal fluid service".
