Cracked and damaged vessels can result in leakage or rupture failures. A maximum working pressure (ps) of not more than 30 bar, and a ps.v (the product of ps and the vessel's capacity expressed in litres) of not more than 10,000 bar.litres a minimum working. Pressure vessel requirements vary quite considerably over the 50 states although virtually all have legislated that pressure vessels should be manufactured in accordance with asme viii, and none appear to have any legislation that supersedes the bpvc.
