<p>An explosion resistant metal tank (10) for pressurized liquid fuels, such as propane, having a hemispherical head (11 and 12) at each end and its only fabrication junction a circumferential welded seam (13) about its midsection, and containing a tightly packed mass of layers of expanded metal sheet (30) in heat conductive contact with substantially all of the inside surface of the container. The process for making such a container includes preparing two drawn metal pressure head sections (11 and 12), fitting one head (11) with a pressure-reducing valve (18) and a conduit through such head, extending a tube (23) from such conduit downward along the wall and beyond the welded seam (13) to an open end in the hemispherical head (17) of the other half section (12); trimming a tightly rolled coil of expanded metal sheet (30) to fit substantially exactly the inside surface contour of the tank (10) with heat conductive contact between the expanded metal and substantially all of inside surface of tank (10), welding the two half-sections (11 and 12) together along the circumferential edge portions while the coil is inside the container, and stress relieving the weld without melting any substantial portion of the coil (30).</p> |
