Hello, Is there any calculation dictated by ASME on UG-34 sketch m for example. Of course "t" of flat head you can find, but retaining rings or threads in different sketches, is there any "approved" calculation procedure?

THX, It's true API doesn't prohibit other designs as well (read that later), my last question would then be: what are ways of calculating thoose designs? FEA?

Hopefully tank experts can help me here. I'm not API designer (I use ASME and EN) but I got a project to check and thought I could learn something new in process. A tank is API 650 19m diameter with dome roof. Dome roof as I can see has radial and circumferental structers (rafters and girders)...

SO basically use the table, depending on E and weld type see what scope of testing you need?

I'm talking about circumferental weld between seamles pipe (shell) and seamless head

I have a question ragarding UW-12 when head and shell are seamless. If I understood correctly joint efficiency E=1 when spot radiography requirements of UW-11a5b are met. But if I preform no radiography or do not met above requirement E=0,85? Also if one uses weld type no. 3,4,5 or 6 E=0,85?

Agree with XL83NL, use ASME Materials, though a lot of manufacturers are now giving dual certificate. 2.2 for non pressure parts will be fine, unless in some off shore projects

THX, That is the main problem, thoose numbers we got, basically 17kN when you combine vector in one direction, look very strange, almost impossible looking at entire pipework. Trouble is we are only hired to do vessel, and price is going up for huge legs or skirt. I managed to found this...

Hi, Maybe this was answered before but I don't have luxury of time to search entire forum, so hopefully I can get some help. We got small, relatively standard vessel to design. We later received forces and moments on nozzles, one moment, circumferential one, was 5.5 kNm and that forced us to...

Thx for answer, yes we put quite a big radius but I was wondering if there is some special section in ASME on this, obviously there isn't.

I have a question considering weld that is both circumferential and longitudinal. Basically part of pipe needs to be cut down and they welded back together,between welds in both direction there is a radius of course. My question is: is there similar examples in ASME to look in to it?

Can you instruct me where in ASME code is calculation for fillet weld size (throat size). I have two plates, one of top another, same thickness, and a = 0,7 x t equals decimal number. (12mm plate on 12mm plate, 0,7x12=8,4). Of course that is max. "a" you can use since going with there is no...

Exactly, that is the main problem, angle is afwul. In ASME VIII there is an example of similiar problem and it's hanled like on the image, basically nozzle is welded like weldolet.

Hi, Can someone share examples of weld shape between connector and shell at an angle like on the image: thx in advance

Hi, I need to create weld beads and weld preparations, even though I'm currently working in Solidworks, and it has less options than Catia, in spare time I returned to my first love :) Catia. So my question is: how to create weld in weld design for cylindrical parts. I'm googling it, but all I...
