I have tried to look for some tips about this specific problem, but my doubts are still there. So, here it is... In attachment I'm posting the geometry of a pipe array that will work as a steam heat-exchanger in an atmospheric melting tank. The pipe arrays are made up of an upper and lower...

I'm afraid that we will have to proceed with cutting anyway. But what about the deformation after cutting?

I have a question that's puzzling me this evening, and any hint would be really appreciated. I am dealing with a torispherical head that has to be delivered into two halves, for transport issues. In attachment you can see the geometry, and consider that it will be manufactured from plate, A516...

Talking about Cirsoc 102, Argentina design wind code: I have to design a steel stack, and I'd like to translate the Cirsoc static pressure into an ASCE-07 equivalent, in order to adopt ASME-STS-2000, but it seems to me that something is not working. As far as you know, is Cirsoc more...

How would you specify a hot forming of an helliptical head (let's to request the supply a dia=1000 thk=22 head). Is there a norm to be recalled, in order to be sure that the heat treatment is applicable and coherent with my application? Thanks!

TomBarsh, I'm afraid that Teflon might suffer viscous deformation if the temperature rises above 400 °F. I need a material that can resist up to 400 °C.

Hi there, here I am with another question. Our Belarus client has sent us his piping dimension, stating that this is what he finds easily on local market. Now, I have checked briefly and I can't match his outer diameters neither with EN standards, nor with ANSI/ASME. I have also checked JIS...

Stanweld, I agree with your suggestion: we are actually using Sa-516 Gr70 for each "plate-shaped" details, such as shell courses and bended profiles. The problem is that some reinforcing external profiles (L shaped, C shaped and IPE profile) should be bended and welded on-site, because some big...

I'm looking for an alternative material to be used instead of Lubrite self-lubricated bearings. Infact, it looks like that this "lubrite" material is not easy to be found and purchased... What would you suggest to use, if you had to find a flat pad suitable for T=400°C , with a vertical load of...

Hi there, this is my first post here! I have been digging in the search results for a while, but I could not find what I'm looking for, so here I am. I'm dealing with MDMT issues, and so I have to find the exact reference on ASTM standard, stating that A36 can (or cannot?) be normalized. On...
