In evaluating the load capacity of a nozzle on a propane tank it appears that the weld strength of the connection could be a primary consideration. I typically use 0.928k per inch of 1/16" fillet weld for 70ksi electrodes for new welds, (0.3 x nominal tensile strength of weld material x effective area). The actual weld size isn't called out anywhere on the vessel drawings so I'm conservatively assuming 1/8" because the thinner of two connected parts is about 1/4" thick. What would be the likely nominal tensile strength of electrodes used in 1958?
I'd like to be able to report to the client that the 4" diameter nozzle is attached securely enough to the vessel shell (0.85" thick A212-B steel) to support a 5000 pound load. Without adequate info assuming a 4" standard weight pipe (4.5 O.D.) circumference is 14". 14 inches of 1/8" fillet weld with E70 electrodes good for 26,000 pounds, so 5000# seems not a problem, but need to be more specific.
I can't find much about weld strength in 1958.
