All,
I have an application where the design temperature is between 1100F and 1150F. In Section II, Part D, there are two rows dedicated to SA-312 TP316 "smls. & wld. pipe" (#32 an d#33) The first row has a creep temperature that begins at 1100F (note T8) and the row below begins at 1150F (note...
Engineering Tips Community,
I have an application for a Section VIII, Division 2 vessel using stainless. My background Div2 is carbon steel and I know that some of these are better than others for Division 2. What high-yield stainless steels are readily available for Div 2?
ASME Community,
I ran into a situation recently where I wanted to use a B16.11 boss connection instead of a half coupling; however, the companies that supply fittings want to charge an obscene amount for them. I looked up boss connections in B16.11 and they're identical to half couplings with...
All,
Today I had a situation where I was over-ridden regarding the use of a full-pen weld on a high pressure (6000 psig) nozzle versus a partial-penetration bevel weld with a small fillet weld on the opposing side. The computer program said a partial-pen weld was okay, so management decided to...
I am designing a 54" Appendix 2 flange and am trying to size the fillet radius 'r' in Figure 2-4. My flange resembles the one in sketch 6 of 2-4. Note (3) at the end of Figure 2-4 says "Fillet radius r to be at least 0.25 g1...". My g1 is 4.75" thick, giving me a radius of 1.188". Yet in...
All,
I've been addressing the changes in UG-44 regarding flange external loads by designing said flanges to Appendix 2. It has been strongly suggested that instead we just put in the quote and on the drawings, in large font, that the flanges are designed for zero external loads and it is the...

I am designing a vertical vessel which has nozzles with inner diameters that are more than 25% of the vessel ID. Is there a way to build a vertical vessel with large openings (>25%) without using Part 5?
All,
I want to know what the difference in burden for the User is between §VIII, Division 1 and §VIII Division 2, Class 1 (Assume that there are no fatigue calcs). I’ve read the requirements for the UDS and nothing stands out as excessive, but I’d like to hear input from others.
