Stainless Steel Tank Shell - Tank Components Paul

Shells are the biggest part of your tank and therefore a big priority.They often house other critical steel tank components,such as manways or heat transfer surfaces,that can make or break the tank for your customer..We fabricate tank shells to fit your specifications,regardless of width or length.Stainless Steel Storage Tanks from Precision Tank,Inc.Vertical storage tanks are available in either cone bottom (CB) or flat bottom (FB).Chemical storage tanks are also available in horizontal (HZ) designs.All chemical storage tanks are constructed of 304 alloy stainless steel with a 2B finish or 316 alloy with a 2B finish,and manufactured with openings and fittings as specified by the customer.Seeking a simple formula to find deflection of flat ends Sep 10,2001 flat bottom tanks shell reinforcing plates#0183;As you have both pointed out,a flat bottom on any support is almost theoreticaly not feasible but in practice,for small tanks seems to be quite OK.Maybe 2 mtrs is pushing it but 1 mtr would be expected to be quite ok if say the bottom was of 5mm (minimum API recommendation for corrosion reasons) mild steel.
