Abstract (en)
[origin: US4884708A] A pressure vessel for the storage of gas has a bottom part, a cylindrical jacket and a head part with a neck, these parts are made of a corrosionproof stainless steel having up to 0.06% C, from 1.5 to 6% Mn, from 0.3 to 1% Si, from 16 to 25% Cr, from 4 to 18% Ni, from 0 to 4% Mb, from 0 to 0.35% nitrogen, from 0 to 0.25% Nb, all percentages by weight, the remainder being iron with the conventional low level impurities; following shaping, the interior surfaces are electrochemically polished; a valve with an adapter is provided for adapting dimensions of the valve to the neck, and a protective cap is threaded onto an upper portion of the head part; through welding or a non welded e.g. a threaded connection the adaptor is connected to the valve, and a nut or welding connection connects the adaptor to the neck.
