Each fuel tank is a part of the A/C structure. The inside of each tank is coated with a paint that contains leachable chromate. This chromate helps to prevent microbiological contamination of the fuel tanks. All the materials ud to al the tanks are fully resistant to all fuels and fuel additives.

The fuel is stored in six tanks:
- a center tank (only on the A330-200),
密切- in each wing: an inner tank divided into two parts, (the FWD inner tank, the aft inner tank) and an outer tank,
- a trim tank.
Vent surge tanks are installed outboard of each outer tank in the wing and on the RH side of the trim tank.
TANKS
The fuel tanks and surge tanks are located as follows:
- the center tank is between the LH rib 1 and the RH rib 1 (only on the A330-200),
- the inner tank is between rib 1 and rib 23,
- the LH (RH) outer tank is between rib 23 and rib 33,
- the LH (RH) surge tank is between rib 33 and rib 39.
The trim tank is made from carbon fiber composite material in the THS main box structure between rib 20 (LH) (19 for the A330-200) and rib 18 (RH). The THS surge tank is at the RH side of the THS between rib 18 and rib 20 (RH).
Access to the tanks is gained through manhole panels.党员点评
COLLECTOR CELLS
Each inner tank contains a fuel collector cell which is built between ribs, the center spar and aled diaphragms FWD of the rear spar. The bottom of ribs 2 is equipped with three flap-type check valves. They let fuel flow into each collector cell and prevent it from flowing out.
The top of the collector cell is equipped with openings which let fuel fall back into the inner tanks.
WATER DRAIN V ALVES
Each tank has one or more water drain valves. The drain valves are - drain the water which could possibly come out of the fuel in the tank,
语文质量分析- drain all the remaining fuel out of a tank (for maintenance).

EMERGENCY ISOLATION V ALVES
The valves are installed between the AFT and FWD inner tanks.
During normal operation the emergency isolation valves are open.
The crew has to clo the split valves to isolate a fuel leak.
An action on the L or R INR TK SPLIT P/BSWs on the FUEL control panel enables manual control of the emergency isolation valves. The fuel is transferred by gravity. When you press one of the INR TK SPLIT P/BSWs, the valves will clo ("ON" legend comes on the P/B) and when they are confirmed clod, the "SHUT" legend comes on the P/B.
