A compressed natural gas fuel tank for vehicles employing internal combustion engines. A fuel tank of heavy gauge metal is interposed within the vehicle frame as an integral portion thereof. Overlay channel members are welded or otherwise affixed to the tank and then welded or otherwise affixed to the side rails or channel members of the vehicle frame. The tank, of heavy gauge metal and non-circular cross section, is also welded or otherwise appropriately affixed to the vehicle floor. The tank is capable of receiving natural gas at high pressure levels, while also serving structurally as a frame element, providing continuity of the side rail members of the frame, while also serving to further interconnect the vehicle floor with the side rails. Also presented are tank assemblies in which a tank housing receives a plurality of cylindrical pressure tanks of composite material construction. The cylindrical tanks are nested within the tank housing, which also serves as an integral part of the vehicle frame. A manifold with inlet and outlet valves interconnects the cylindrical tanks.

A dual-gas fuel tank assembly for a fuel cell driven vehicle wherein the fuel tank is interposed within the vehicle frame as an integral portion thereof with the tank assembly having a plurality of cylindrical pressure tanks of composite material construction for containing oxygen gas and the cylindrical tanks being partially nested within the tank assembly housing to leave substantial space around the pressure tanks for storing metal hydride powder therein for producing hydrogen gas to the fuel cell upon application of heat thereto.

A method and apparatus of separating a vessel which is partly welded to a tubesheet of a tube bundle, includes removing the weld seam and reducing the wall thickness of the vessel until only approximately 1/8' of wall thickness remains and thereafter parting the vessel from the tubesheet by extruding the remaining wall thickness using a wheel cutter. The wheel cutter itself comprises a uniform thickness disk having a frusto-conical, cylindrical and subsequent conical portion on its outer periphery, the conical portion tapering to a greater extent that the frusto-conical portion.

Method to part welded vessel sections without violating internal

A method and apparatus for pressure testing a large vessel utilizing a base enclosure having a base ring of the same diameter as the pressure vessel. The base enclosure includes a base plate welded to the base ring and beams under the base plate for supporting the weight of the base enclosure as well as the portion of the vessel to be tested. The vessel is fabricated in or divided into half portions with each portion being connected to a base ring for separate testing. This eliminates the excessive weight that would be experienced if the vessel were to be pressure tested as one unit, particularly in the case of hydrotesting where the vessel is filled with water.
