Scope of Radiogrpahy
Scope of Radiogrpahy
(OP)
100 % RT on a A333Gr.6 piping weld joints with hazardous service of NGL at low temp. -30 deg.C & 40 kg/cm.2, is justifiable or not?
Some standards support it and some not !
For better reliability and safety involved, we have carried out 100% Radiogrpahy of weld joints
Whats is your opinion

RE: Scope of Radiogrpahy
So, you can certainly justify any construction/inspection as being "above Code", indicating (in most cases) a better quality product (applies to any product manufactured under some governing code).
As to whether the particular design code(s) applicable to your situation requires full RT or not, that is another issue.
RE: Scope of Radiogrpahy
in our case, we have given more emphasis ro safety and reliability an upper edge over the standard,which in my opinion is a guideline and not always a mandatory requirment.
RE: Scope of Radiogrpahy
Just don't think that 100% RT is going to come at zero additional cost. There will be false positives and unnecessary re-work. But with 100% RT, the welders will definitely know that someone is watching...
RE: Scope of Radiogrpahy
Knowing that RT is in QAP, welders do get more attentive and the repair rate eventually has fallen.
RE: Scope of Radiogrpahy
Given your use and service temperatures, I can't see anyone making a particularly strong argument against what you're doing.
