    Threaded coupling in flat cover (manway) UG-45

    IdanPV Apologies Idan, I accidentally skipped your response. Thank you very much for answering. I see that Table UW16.1 is even more stringent than the UG-45 table; now the 'UW-16(f)(3)(-a)(-6)' makes more sense to me. Logically, it seems advisable to discard the use of Class 3000 in flat...

    Threaded coupling in flat cover (manway) UG-45

    DriveMeNuts, The only reason I said it wasn't an option at the moment is because if I switch to the S6000, there is no problem to solve. English is not my first language, and I may express myself poorly; again, that is not a reason for you to come and judge people. I understand that, besides...

    Threaded coupling in flat cover (manway) UG-45

    DriveMeNuts. I think you should be more kind and not assume things about people. I never said that I manufactured that container. From the responses you give, it doesn't seem like you have a clear understanding of things to speak to me in that way (You failed to answer any of the questions I...

    Threaded coupling in flat cover (manway) UG-45

    GD2, Thank you for your reply. So, If I do this, is it enough? Sorry for doubting so much, but I want to be sure before closing the topic.

    Threaded coupling in flat cover (manway) UG-45

    DriveMenuts, Is this wrong? Or am I misinterpreting it? GD2, What do you understand from that interpretation? (Even when it comes to a manway, they must comply with UG-45, but the formula is different (t_UG-45 = t_a). I'm not saying that compliance is unnecessary; I'm saying that the...

    Threaded coupling in flat cover (manway) UG-45

    Thank you for your response, to both. GD2, According to that, if I am going to use a 1/2" S3000 threaded coupling, which is equivalent to a 1/2" Sch 160 pipe, I should only make sure that the pipe complies with UG-27 for my design conditions? And then, I just need to check UG-39. I want to...

    Threaded coupling in flat cover (manway) UG-45

    DriveMeNuts This coupling is simply a vent, it will not be subjected to external loads. Maybe I expressed myself incorrectly before. This is why I believe that UG-45 also does not apply. Is this correct?"

    Threaded coupling in flat cover (manway) UG-45

    IdanPV What is visible is the manway of the filter with the threaded coupling 1/2"NPT welded on the flat cover. The vessel is manufactured with a seamless pipe NPS 8" I want to see if I understand correctly everything you have been telling me: According to ANSI B16.11, the 1/2" Class 3000...

    Threaded coupling in flat cover (manway) UG-45

    david339933 For now that's not an option and i want to understand if it is excluded or not, that is the most important for me right now.

    Threaded coupling in flat cover (manway) UG-45

    IdanPV The outer diameter of 1/2" class 3000 couplings is 29 mm, and since the outer diameter of a 1/2" NPT thread needs to be the nominal size of the pipe (21.3 mm), the thickness is 3.85 mm. However, PV Elite gives a slightly lower value (3.62 mm), which also does not comply with UG-45 if...

    Threaded coupling in flat cover (manway) UG-45

    Thank you for your answers Christine74 I've seen that clarification before, but I don't quite understand it. Could you explain to me what it means? I understand it as follows, "the standard thickness of the Class 3000 threaded coupling verified for internal pressure is already sufficient, and...

    Threaded coupling in flat cover (manway) UG-45

    I have seen many posts on the forum about this topic, but I haven't found one that really answers this question. I will try to be as clear as possible: I have a flat cover that I designed according to UG-34 for a filter, which serves as a manway to change filter elements. If I place a threaded...

    Swing Bolt from standard flanges

    I never said i did not know that. That's why i am looking for help in this issue. Thank you for your help.

    Swing Bolt from standard flanges

    Than you for your reply. Is for a 12 in diameter filter for a design pressure of 3 kg/cm2. SS304L

    Swing Bolt from standard flanges

    Thank you for tour reply. I am traying to leaen how to design them so i can make that part of the vessel. I am having trouble finding information about this. I thought that there was some kind o guide or Excel sheet to design them
