I think it depends on company size, if you can always rely on the internet connection and how much variation you have with use. So a large company who has lots of people working the majority of their time on CAD I think you cant beat having a workstation under each persons desk. But for a...

I am trying to design a flange using Div 1, Mandatory Appendix 2 Bolted Flanges. But because of the gaskets and bolts the flange is getting very thick, which I am trying to avoid Most of that is driven by using the bolt load, I know using Torque to set Bolt load is quite inaccurate especially...

Hello All, Is there an equivalent European standard to EN13445 for fired boilers? I can't seem to find one. Any help apprecaited.

M10, but I also have other items with different threads so I wanted to understand the rules.

IdanPV, thank you, I didn't realise this list of interpretations existed. I will check on that for future questions. Anyone know why don't these interpretations get rolled into updates on the Code? I appreciate every one cant be added, but in my mind this one is actually changing the code not an...

Hi Geoff, thanks for your answer. When you say partial depth what do you mean? To take it to extreme, if I only use a small number of threads on the sensor the pressure could be enough to damage these and blow the sensor out. So I am surprised if this isn't covered in Div 1 somewhere, but UG43...

There are a couple of different things. The smallest in diameter is an M10 thread at the moment. There are a couple of different threads though, and thing might change in future, so knowing where is states the rules so I can understand them would be great. Thanks

Hello All, To clarify I am looking for holes that go into the pressurised area of the vessel, for example to add a pressure sensor. B1.20.1 is listed in UG-43, So I know i can use threads here, but they don't include metric threads, which some of my bought in components have. Where does it...

Hello All, From reading BPVC 2023 Div 1. The only reference I can find for threaded connections is UG-43. The way I understand this we can only make a connection to the pressure vessel if the thread is listed ASME B1.20.1. Is this correct? Any help appreciated. Thanks Gavin

Hello All, I am working on a design using Stainless Steel tube and I need to fix the diameters for a production intent design. Ideally using a standard size and avoiding any turning of the OD or ID. The product needs to go through ASME certification BPVC VIII, so I need to know the ASME...

Are those values Minimum stress? So Y in the Asme standards? So Kamprofile seals require between 10-40 Ksi (69- 236MPa) Is the range due to different Kamprofile designs/thickness or is it that to seat properly it needs a Minimum of 10? Thanks

Hello Both, Thank you for the replies, 1. Yes, by the average term I meant adding (Am + Ab)/2. I guess I cant understand why the Bolt load, W, would be related to the minimum area required of the bolts. I would have thought we should work the out the minimum area, check the proposed design...

Hello All, I am seeking advice on understanding this, I have scanned through the forums and found some similar lines of enquiry, but I still can't understand it this appendix fully. This is based on the 2023 release. I am pretty new to ASME and very new to pressure vessels. 1. Equation 5. (Pg...
