Radiography examination in D fluid serrvice
taking in advance of this theme about examination for D fluid service. I need a clarification about radiography requirements, consulting B 31.3 , 1996 and 1999 rev , this topic is very clear in table 341.3.2 but in 2008 rev the table is different and it does not very clear to me.
We need o we dont need radiography for this service.? The code has not change this aspect?
Thanks for your attention

I would like to clarify few points on the interpretation 16-01 of ASME B http://31.3- Para 341.3.4 Progressive examination.

The question for Interpretation 16-01 is:

In accordance with ASME B 313.3-1996 Edition, Progressive examination, if the defective weld is repaired and found defective again, repaired a second time and again found to be defective, is it necessary to examine two additional items for each failed repair?

And the answer is "No. See Para 341.3.3"

Para 341.3.3 says, Defective Components and Workmanship. An examined item with one or more defects (imperfections of a type or magnitude exceeding the acceptance criteria of this Code) shall be repaired or replaced; and the new work shall be reexamined by the same methods, to the same extent, and by the same acceptance criteria as required for the original work.

I have 2 queries :

1. The above Para does not deal about the progressive examination, however specified that the repaired joint shall be re-examined by the same methods, to the same extent, and by the same acceptance criteria as required for the original work. And if the evaluation of the repair joint is as same as the original work, the requirement of progressive examination according to Para 341.3.4. also applicable for the repaired joint. Please clarify..

2. If the defective weld is repaired by different welder #2 and not the original welder #1, and produced a new indication more than acceptable limit (repair), the same evaluation answer for the interpretation 16-01 is applicable? Or the progressive examination for the welder # 2 will be applicable?

appreciated, if anyone can clarify the interpretation of the above.

1. As per the scope defined in ASME B31.4 Fig 400.1.1-1 we can use the pipeline code inside the Tank Terminal. If we use ASME B31.4 for Tank Terminal with Pumping station, can it be a manned area or it should be an unmanned area ?
2. Can we use ASME 31.4 on onsite Tank and pumping station where there are other auxiliary facilities like Power Station, Control Building, Substation, booster pumps, Main oil transfer pumps near by but within the main facility boundary ?.
