Standard NF EN 12285-1: For underground cylindrical storage tanks containing flammable and non-flammable liquids polluting water.
Standard NF EN 12285-2: For overhead cylindrical storage tanks containing flammable and non-flammable liquids polluting water.
Standard NF E 86-410: For cylindrical storage tanks intended for water storage.
CODAP or NF EN 13445: For pressure tanks.
CODRES or NF EN 14015: For vertical cylindrical storage tanks. CODAP: For pressure tanks.
The tanks can be: - Single-walled: The single-walled tank is formed from a single impermeable envelope and constitutes the inner envelope of a double-walled tank. - Double-walled: The tank is composed of an inner shell for storage and a second shell (which covers 97% of the nominal volume of the inner tank) welded around the inner tank. This double jacket is connected to a leak detection system in order to constantly monitor the integrity of the tank.
The dimensions are indicated on our technical sheets in the section Download
A compartmentalized reservoir is a reservoir with several unique fluid storage spaces inside.
The leak detector continuously monitors the tightness of double-walled storage tanks. For more information, please refer to our section Download
For underground tanks, the connection sleeves are located on either side of the manhole. For overhead tanks, the connection sleeves are located on the domed bottoms at each end of the tank.
A fill limiter is a mechanical safety device for environmental protection intended to prevent any overflow of liquid when filling a tank. The filling limiter is mounted on the filling pipe inside the tank. For more information, please refer to our section Download
The slab frame is a metal frame that helps anchor the tank since it will be embedded in the concrete base to counter Archimedes' thrust. It is secured to the tank at the factory using galvanized cable and plastic sheathed anchor belts. The slab frame also improves safety because it avoids human intervention at the bottom of an excavation during the installation of the tanks. For more information, please refer to our section Download
For underground tanks, the earthing lug is located on the manhole ferrule. For overhead tanks, the grounding lug is located on the cradles of the tank.
Yes, the manhole trays can be equipped in the workshop with the different pipes or accessories according to your needs. (Filling, Suction, Gauge ...)
A tank built according to standard NF EN 12285-1 is designed to support a backfill height of 1.5m on the upper generator of the tank. A greater backfill height requires further study.
The tank is not designed to accept the loads induced by traffic. In this case, it will be necessary to make a distribution slab or carry out an additional study.
The tonnage scale is sent with the invoice for each tank.
