 | Underground Cylindrical
CYLINDRICAL TANKS FOR UNDERGROUND INSTALLATION BUILT WITH FIBERGLASS REINFORCED PLASTIC
Underground cylindrical tanks are fabricated using the Filament Winding Process in accordance with ASTM-D3299 Norms, using resins of high chemical resistance reinforced with glass fibers of the unidirectional, bidirectional and multidirectional types. | Body structure as well as covers and supports are calculated taking into consideration eventual loads. Tanks are designed for installation underground on a flat, even surface, with no bumps or irregularities, where the tank body will rest. Standard accessories are a manhole with cover, gasket and bolts, a vent, loading and drainage fittings, lugs for handling, inserts for anchoring, and a nameplate. Tanks are delivered with installation and preventive inspection instructions plus calculation documentation.
Table below shows standard dimensions and capacities. Some differences may be incorporated in dimensions and accessories according to requirements.
To properly define the structure and resin type so as to satisfy a specific condition, it is important to provide the following parameters: Contents of tank
Concentration
Specific weight
Operating temperature
Maximum temperature
Seismic characteristics of location
Eventual overloads |
