    dished end with small convex

    "The shallower heads are often not ASME heads, because they do not meet the dimensional requirements of ASME as to dish radius, etc. but are still commercially available." That's what i'm talking about, if they do not meet the dimensional requirements of ASME and PED and DIN how they are...

This type of vessel is not covered by PED, but they are supervised by technical office inspector, and inspector wants to see a strength calculation. Some firms make a storage vessel for gasoline using...

    dished end with small convex

    It's some kind of torispherical head similar to DIN 28011, (you can see here for example: http://www.weisstaler.de/en/sites/weisstaler.html)but flattened, with small ratio H/D. It looks like Standard-type/flat dished head (3rd row on this web site) Andy

    double wall vessel

    Hello, I have a question. Are there a minimum walls thickness limitation in double wall vessel in BSI regulation? I am a designer from Poland and I have to design a double wall vessel acc. to BSI. In Poland there is a limitation of thickness, 5mm for internal and 3mm for external shell. I dont...
