Dear all, could you suggest a catalog for standard fittings selection?

I’m looking perhaps for elbows, threaded connectors or joints for pipe sizes up top 3/4’’ made of stainless steel to carry liquid fluids.

Thanks, I will appreciate your help.

I am currently in the realization of radiographs for the release of 6 tanks according to API 650. Code that requires the use of IQI type holes.
At the moment the following concern arises to me, At the time of the accomplishment of the x-rays in the seams in T with different thicknesses, how many IQI are required?

Dear Members,

I'd like to share with you a technical issues in a project I'm working in. A fire fighting piping system 20" diameter distributed in to all project's area (Tank farm area, Building area, also on pip rack) they are already completed and no one was following the construction team and no QC (never been inspected or tested by NDT), and all welders are not have been tested for the qualification (WPQ) also the WPS not have been made. the material is CS A105.
what should the QC Engineer/Inspector do for the assessment, quality and integrity of this piping system,
what are the requirements, principals and standards should the QC follow?
FYI the system is new construction and not have been put in-service.
Waiting for your technical and professional advises.

Best Regards

Khalid

Regards,
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 ?.
