摘要： A system includes a plurality of lifts configured to couple to a storage tank about the storage tank, a reservoir to store compressed air, and a manifold. Each lift includes a hoist, a coupling to extend between the hoist and a roof of the storage tank, an inlet conduit to be coupled to an inlet of the hoist, and an outlet conduit to be coupled to an outlet of the hoist. A pressure difference between the inlet of the hoist and the outlet of the hoist spools the hoist. The manifold fluidly couples the reservoir to each inlet conduit and fluidly couples each outlet conduit to an exhaust. The manifold includes a plurality of outlet valves, each coupled to one outlet conduit of the plurality of outlet conduits and configured to regulate flow between the outlets of the plurality of hoists and the exhaust.

摘要： An internal floating roof for a storage tank includes a rim, a first plurality of girders, including a first girder, a second plurality of girders, including a second girder, a deck sheet, a first cap channel, a second cap channel, and a pontoon coupled to the first girder. The first plurality of girders extend in a first direction across the rim, wherein the first plurality of girders comprises a first girder. The second plurality of girders extend in a second direction, cross-wise to the first direction. The deck sheet is disposed on a first top surface of the first girder and a second top surface of the second girder. The first cap channel is coupled to a first top channel of the first girder. The first cap channel comprises a first foot configured to press a first edge of the deck sheet against the first top surface of the first girder. The first foot is welded to the deck sheet along a first length of the first cap channel. The second cap channel is coupled to a second top channel of the second girder, wherein the second cap channel comprises a second foot configured to press a second edge of the deck sheet against the second top surface of the second girder. The second foot is welded to the deck sheet along a second length of the second cap channel.

摘要： A trolley includes a body and a side block coupled to the body via a pivot arm and a spring. An adjustment knob adjusts a position of the side block relative to the body. A first plurality of rollers are coupled to the body and roll along a first roller recess on a first side of a length of a cap channel. A second plurality of rollers are coupled to the side block and roll along a second roller recess on a second side of the length of the cap channel. A first welding torch bracket positions a welding torch at a first interface between the first side of the length of the cap channel and a first deck sheet as the trolley traverses the length of the cap channel.

摘要： A batten bar is configured to secure first and second adjacent flat panels to a structural framework. The batten bar includes first and second inside legs, first and second outside legs, and a plurality of apertures disposed along the length of the batten bar. The first and second inside legs define a central channel. The first outside leg and the first inside leg define a first seal recess configured to receive and retain a first seal. The second outside leg and the second inside leg define a second seal recess configured to receive and retain a second seal. In an installed configuration, the first inside leg and the first outside leg are configured to contact the first flat panel along a first common plane, and the second inside leg and second outside leg contact the second panel along a second common plane.

摘要： A roof panel of a sealed floating roof for a storage tank includes a first frame segment and a second frame segment. Each of the first and second frame segments includes a first depression configured to abut an adjacent top depression of a respective frame segment of a respective adjacent roof panel to form a walled trough to guide an automatic welder along a weld joint during a welding process. The roof panel also includes a panel component. The panel component includes a top sheet and a pan-shaped bottom sheet coupled to the top sheet. The pan-shaped bottom sheet is coupled to a respective upper lip of each of the first and second frame segments.

摘要： A method for forming a sealed floating roof for a storage tank is disclosed. A plurality of roof panels are positioned adjacent to one another such that respective depressions of adjacent roof panels disposed adjacent to one another form a walled trough at interconnections of the plurality of roof panels. A self-propelled automatic welder is positioned and guided within the walled trough to make a weld joint at the walled trough, and thus forming the sealed floating roof.
