Thank you Duwe6 and jte for clearing that up. I can see the use of the vessels in question as a distribution system, also the vessel to which I am referring is not used as a portable compressed air system. It is merely a means to distribute and offer volume to reduce fluctuations in pressure...
Ok, let's say that the vessel is much larger than 6" ID (30" for example) and holds a pressure of 100 psig. Would the "air pig" vessel need to be properly tagged and designed according to Section VIII?
I was researching this particular standard because of the discrepancies I found in the WLL "Working Load Limit" stamped on the shackles we use for lifting. At first I believed it to be different manufacturers have different WLLs...I found this not to be true, however. This standard came about...
I have a P-4 data report that lists a material specification as SA 299N. I cannot find any information on what the N after the number stands for. Any thoughts?
