Hi All, Thanks for the quick responses. Sorry, this is the only photo I have. The tube OD is 1". The slotted ferrule is about 3/4" long. This appears to be a self-flare fitting put out by LDI industries. Back in the day I believe the company was called Flodar. See images I pulled from...

Hi All, Can anyone identify this type of tube connection? I am looking to find some literature on this. Note the slots cut in the ferrule... This comes from a 1500 psi HPU - circa 1960. Thanks, 22west.

All good now. I will contact the consultant and ask them why they located their SCL in that location. Thanks to all, 22west

Ok yes, I have seen that before - ideally more with the inside fillet and rounded outside edge. This makes sense to me too. But what has been done is more like image attached . . . so strange to me...

Thanks NRP99 for the reference on report requirements, I will check into that. On the topic of fatigue - this is indeed a report on fatigue life, and these oddball SCLs are driving the life. In this case of fatigue evaluation, how do these types of SCLs come into play? Thanks, 22west

Hi All, Thanks for helping me with this "sanity check". The oddball SCLs are actually closer to the inner main wall than I show on my previous sketch, where it is more like drawing the SCL through the inner corner which is usually a nozzle red zone. See attached image. I pulled this FEA image...

Hi All, I just received a consultant's report on a pressure vessel and for each nozzle three SCLs were examined. See attached image. I understand the need for lines 1 and 2 but what is the point of line 3? It is not on the pressure boundary - so why examine that area? Note that the weld at...

I am digging up some more details on this. The image below is the material props - take from a sample of each welded piece. The top row is the shell composition and the bottom row is the lug composition. I keep digging. I will try to find out what rod was used. . .

Hi, Below is a picture of a recent re-weld at the base of a lug. This is an old 1950's structure with not a lot of good documentation - both the lug and the shell are thought to be mild steel. The weld was re-done by a certified structural welder after some cracking had been found. The welder...

Hi, I am looking to see if anyone has a 1956 copy of ASME Section II where they could look up and tell me the published allowable stresses for both A212A and A212B firebox steels. I would also take something "in the vicinity" of 1956 as well. Thanks, 22west

Hi all, I did not get these responses until now because I was monitoring my emails and not the website. It seems my "reply alert" is not working. A note of thanks for the helpful responses. Not sure about the reason for the "all going to die" comment. . . Cheers, 22west .

Hi All, I am looking at a list of old boiler plate steels and find they have a designation of "T" at the end. Example A212-1957T. I believe the 1957 is the year produced (and please correct me if I am wrong on this) - does anyone know what the "T" represents? Reference image attached...

Hi, I am performing a S8D1 flange calc on an existing PV cover (flange + torispherical head). I am trying to establish the most applicable flange -to-head weld scheme from Figure 2-4 - I think it is sketch (11), full pen with backchip. I attach an image of the flange weld detail from the...

Please forgive my lack of ASME code knowledge in this question, Does ASME Sect VIII div 2 recommend the use of Von Mises stress plots to evaluate fatigue life? From some casual reading on-line I get the impression it does, Intuitively I would expect a principal stress plot to be a more accurate...

Does anyone have any operational experience with the Samsung Techwin centrifugal compressors? Specifically the larger SM series units. There seem to be a lot of these in China, Korea and Russia - but not too many in North America. They have an office in Houston. Samsung have been making their...
