    Non-circular reinforcing pad EN 13445 / ASME VIII-1

    Hi, thank you all for the feedback. Are you also familiar with the EN 13445 requirements on this matter?

    Non-circular reinforcing pad EN 13445 / ASME VIII-1

    Hi, I would like to ask you, with reference to the image below, whether the reinforcing pad in option 2 (non-circular), which features an unwelded portion, is acceptable under EN 13445 and ASME VIII-1. In my opinion, the "extra" area outside the circular projection of the reinforcing pad might...

    Applicability of SA-788 S12 for SA-182 F316 HUBBED TUBESHEET

    Hi, Is supplementary requirement S12 of SA-788 applicable to hubbed tubesheet in SA-182 F316? This is applicable for example to SA-765 forgings (explicitly recalled in SA-788), but I would like to understand if this is technically needed also for SA-182 F316 forging. Thanks in advance

    SA-182 VS SA-965 for heat exchanger tubesheets and girth flanges

    Dear all, Thank you very much for the clarification, it seems that in Europe there is a bit of confusion on this. Best Regards

    SA-182 VS SA-965 for heat exchanger tubesheets and girth flanges

    SnTMan, Krausen, I agree with you; I have never seen a heat exchanger drawing with SA-965. I just wanted to understand if there was any specific detail in the code that would make it incorrect to use one material instead of another. The same applies to SA-350 and its equivalent for...

    SA-182 VS SA-965 for heat exchanger tubesheets and girth flanges

    I reconnect to this thread. Is it correct to order a tubesheet or a girth flange for a heat exchanger in accordance with SA-182 instead of SA-965 for SS316? Reading the specifications, it seems that both are applicable, with the difference that SA-182 is limited to products weighing less than...

    ASME VIII-1 welding for internal projection nozzle on standard blind flange

    Hi RadiateurFou, The image is a screenshot of the existing equipment drawing not designed by us. We now need to redesign it completely.

    ASME VIII-1 welding for internal projection nozzle on standard blind flange

    ...of a 4" WN welded to above pipe. Considering that the 4" pipe has a thickness of 13.49 mm, the internal diameter of the blind would be (114.3 - 2*13.49) 87.32 mm. In this case, no calculation would be required according to ASME VIII-1, and we can simply follow the pressure-temperature...

    ASME VIII-1 welding for internal projection nozzle on standard blind flange

    I also tried to be polite, r6155. I didn’t mean to be aggressive, and I’m sorry you felt insulted. I was just trying to explain why I thought you were making a mistake in how you formulated your responses. Even though you’re not my father, we can still start over and have a productive discussion...

    ASME VIII-1 welding for internal projection nozzle on standard blind flange

    Why? Could you please explain which paragraph is missing?

    ASME VIII-1 welding for internal projection nozzle on standard blind flange

    r6155, I understand your point of view, and to some extent, I agree with you. What I disagree with is the way you interpret this perspective regardless of context. You cannot know whether I have never opened the code and use the forum to get quick answers simply because I don’t want to reread...

    ASME VIII-1 welding for internal projection nozzle on standard blind flange

    Trestala, IdanPV thank you very much for the suggestions. r6155, I would like to let you know that I have read the entire Div. 1, every page, and I design things far more complex than what I asked about. However, as you should know, unless you are a computer, it is impossible to remember...

    ASME VIII-1 welding for internal projection nozzle on standard blind flange

    r6155, Ring joints are extensively used in high-pressure heat exchanger nozzles with applied external loads, and in our experience, no problems have ever occurred. On the basis of which paragraph is the welding insufficient? My question is quite specific, Thanks in advance

    ASME VIII-1 welding for internal projection nozzle on standard blind flange

    Hi, I have a question about the calculation in accordance with ASME VIII-1 for the configuration shown below: what are the reference paragraphs for the calculation of the standard blind flange with a 4" nozzle inserted as shown in the detail? Being a standard component but modified due to...

    Equipment for performing weld overlay on nozzles smaller than 3 inches

    r6155, some of our clients have experienced problems for integral nozzles (for example in SS) welded directly on a CS shell internally cladded in SS, so simply they do not permit and you have to clad also the nozzle. Unfortunately this is mandatory.
