Hi All, I'm designing a steam trap, It's designed so that it satisfies both PED & ASME standards for min wall thickness etc If I want to formally rate it to say, 600 PSI then as long as it passes the pressure test using pressure test equation for the material class that the end of it? or is...

So are you saying that as soon as a flange is welded to a item that item markings need to be changed to be in line with the flange welded to it? or would the flange markings always be taken as the maximum conditions?

Hi All, I'm designing a steam trap assembly, part of this includes Y-strainer directly welded to a flange The strainer has cast on markings of TMA 500'C, PMA 50 Bar, Material CF8M the Flange will be in stainless steel 316L, being either ASME #150, #300 #600 or EN PN40 Any one of these flanges...

Hi All, Just a quick one, Firstly is the 7mm (6.4mm on some other sources) raised face on the ASME 600# rated flange a requirement or just a recommendation? I.e if I were to machine this down to 2mm would it then affect the sealing properties and therefore the rating of the flange itself, or...

Hi All, I've been doing quite a bit of R&D into Lapped Joint Connections and want to utilise some of these for high pressure and high temperature Steam applications. Most likely up to 50 Bar(g) & 500'C Reading through the standards for flanges, connections etc its clear that lapped joint...

OK Perfect! Why does the Lapped pipe end only appear to be up to PN16 pressure rating? To get a PN40 rating I would need to go for the Weldring or Weld neck collar instead it appears, Not sure I understand why from the dimensions but there you go

Hi all, I'm designing a prototype that is machined from bar with a stub end connection, the idea being that a loose plate would slip over the prototype body and form a lap joint connection. The reasons for this is that we would require the loose flange to be rotated for accurate bolt hole...

The tool is essentially the different ASME flange thickness' as a cut out from a steel plate, you'd fit it over the flange to the correct section, combined with the Nominal bore you'd be able to quickly find the flange class from these two variables, which are etched into the tool itself...

Hi Eng-tips community, This is my first post here so hopefully it's nice and concise. I'm currently doing some R&D for a couple of new products, one of them being a tool to measure the thickness' of ASME Flanges on site, The thickness values (c) in the ASME 16.5 standards are taken as the...
