BULK STORAGE VESSELS Abstract of the Disclosure A bulk storage vessel of generally cylind- rical upstanding shape is formed with a plurality of wall segments which are assembled together in end to end relation to form subassemblies of circular shape which are interconnected along upper and lower edges to provide a cylindrical vessel. Each wall segment in- cludes a curved wall of generally rectangular shape having a flange along upper and lower edges and a vertical end flange at one end. The upper edge flange includes an outwardly extending horizontal flange section and a downturned vertical flange section and along the lower edge, a flange includes an outwardly extending horizontal flange section, a downturned vertical flange section and an inwardly extending flange section which is deflectable for interlocking engagement with the upper edge flange of an adjacent lower subassembly. A first subassembly of wall segments is assembled at ground level and is then elevated to a height sufficient to clear the wall segments of a next subassembly which are positioned therebelow during assembly. Wall segments of the next subassembly are interconnected with the lower flange of the first sub- assembly and the wall segments are supported by this flanged interconnection while the lower or second wall segments are being assembled end to end. The intercon- nected flanges of the two subassemblies are crimped together externally of the vessel.
