konrad,
doct9960's explanation is more logical. The ASme code was developed by North Americans. If you look into the meaning of 'inwardly' and 'outwardly' in an American/English dictionary and combine those meaning to the word 'flanged' (e.g. inwardly flanged), you will make sense in what the...
konrad,
some questions on your thingamajig (sketch #2):
1. what's the material?
2. what are the dimensions and thickness?
3. what are the design conditions (DP, DT, etc)?
4. how do you intend to fabricate it?
5. what is ONE/TUV/BV or OneBeacon's say on this? (assuming they are your AI)
kander,
YOU are the ONLY ONE confused. Why are you making a big fuss on semantics? If you have doubts on terms containing "billion", ask the source of that information. You will probably sound stupid to them, but at least you will have the satisfaction of knowing that the billion means...
doct9960,
Sorry I did not really answer your question. My answer is NO. I do not recommend a locally thick insert plate for heavy wall vessels(greater than 2" thick) or for nozzles in high-temperature hydrogen service.
Shofa,
You seem to imply that some of our experienced colleagues above are the authoritative body in vessel design & construction. [wink]
Would you be kind enough to tell me the specific paragraph in ASME VIII (Div. 1 or Div. 2) where it is mandatory use insert plates or self-reinforcing...

"The reason given for not including seismic load was horizontal installation. Is that correct?"
I don't quite get what you are saying in your above statement. For sure there are horizontal seismic forces and horizontal thermal forces. And how about wind loads? Even if seismic is the...
Looking at some actual photos of the skywalk, it seems there are railings at the back of the structure. Is the skywalk retractable? For maintenance purposes maybe?

asv80,
Are you sure you got "allowable" loads and not "actual" loads from your customer? Many companies provide a tabulation (sometimes formula) of allowable loads for different nozzle sizes. This table of allowable loads are not usually categorized in separate weight, thermal, seismic or wind...
The PE, who would be certifying the Manufacturer's Design Report for compliance, is responsible for reviewing WPS/PQR's. The PE must make sure that the WPS/PQR's are qualified with Section IX and that they are in compliance with the requirements of Division 2. Although WPS/PQR's are not...
Check your jurisdiction (i.e. Dept. of Transportation). Some jurisdictions allow either MC-30 or MC-70 for prime coats.
Here's a guideline from CFLHD... http://www.cflhd.gov/techDevelopment/completed_projects/pavement/prime-tack/_documents/prime-tack-coats-entire-doc.pdf
