PRINCIPLES OF OPERATION
PRINCIPLES OF OPERATION
General
The collapsible fabric petroleum tanks described in this manual are components of a fuel system. Any
size fuel tank may be connected to the system, depending on operational requirements.
Filling
The collapsible fabric petroleum tanks are filled by pumping fuel from tank trucks using the system pump
assembly. Control of fuel flow during filling is accomplished with fuel system gate valves. The tank is
filled through a 4-inch (10.16cm) collapsible hose connected to the tank filler assembly. As the tank is
filled, it enlarges to a pillow shape. Venting of the tank during filling is performed automatically by the
center vent assembly with pressure relief cap.
Discharge
When needed, fuel is drawn from the tank by the system pump and distributed through a network of
valves and hoses to the fuel dispensing facilities. Fuel is drawn from the tank discharge assembly
through a 6-inch (15.24cm) hose. As fuel is drawn from the tank, the tank will flatten. Fuel flow between
the system pumps and the fuel tank is controlled by system gate valves. When the tank is empty, or no
more fuel is needed, the downstream system valves are then closed.
Draining
Hand-operated gate valves on the drain hose assemblies connected to the tank drain fittings control fuel
flow from the tank drain. These valves allow restricted flow of fuel from the tank for sampling or complete
drainage. When preparing the tank for movement, the system pump will draw most of the fuel from the
tank. To ensure complete drainage, the hand drain valves are opened.
