Thank you Mike,
I was not too sure about this. Because this is for ASME VIII div1, but when I looked at ASME VIII div 2, the category D corner joint need at least 10% volumetric examination (Table 7.2, joint category D, type of weld 7) to reach a weld efficiency of 0.85. And so even if the...
Hi all,
With reference to thread292-267966, what would you answer to the following question :
For a set-in 12" nozzle made of welded pipe TP304L Sch80S, that does not have circumferential butt welds in its assembly, Category C fillet welds [such as shown in Fig. 2-4, sketch (3a)] are used to...
Thank you all for your replies.
I just tell the end of the story, for those who would read this topic later on.
We decided to perform a destructive examination on a nozzle, and found out that nozzle fit-up was probably different from what was designed.
I think we saved time compared to the UT...
Hi everyone,
After reading through ASME VIII div 1, some of its code cases, ASME V, and various papers about the subject, I am trying to make up my mind about the most convenient way to inspect the welds connecting set-in nozzles to their duplex vessel.
I would usually stick to the code...
Hi everyone,
Since 2008, ASMEVIIIdiv1 requires that "test pressure and coincident static head acting during the test" is considered in designing a vessel.
I hope I was not the only one to keep an eye on this before code eventually asked for it.
However, div1 does not mention specific acceptance...
gr2vessels,
Thank you much for your advice. It is clear and being descriptive actually helped me.
I think I got it, but your first comment let me think I could miss something.
I agree 'd' is measured in a plane containing the nozzle centerline. But there is still in infinite number of planes...
I have a question regarding ASMEVIII Div1 UG-42
When two similar nozzles are installed on a longitudinal line of a vessel, and both nozzles are radial, I have no problem using UG-42 since whatever the plane I consider, the finished diameter d of the opening (as defined in UG-37) is the same...
