Underground tanks

Underground steel tanks for the storage of oil products, water reserves for firefighting applications and water polluting liquids.

Underground tanks
Horizontal cylindrical single and double-walled tanks for underground storage of flammable and non-flammable water-polluting liquids. Made by using shell plates and dished ends made in carbon steel quality S 235 JR complying with UNI EN 10025, or on request with other types of high quality steel (P275NH, AISI304, etc.). The external and internal joints are tight welded. All components are produced according to rules and regulations in force and in particular tanks are designed and manufactured in compliance with the European Standard UNI EN 12285-1.
Our double-wall tanks consist of 2 tanks, one installed inside the other, creating, as per regulations, a gap between the two tanks that can be monitored with our continuous monitoring systems, guaranteeing tightness over time. All inner and outer tanks are provided tested. Tests are pressure tests and are performed to check the integrity of both inner tank and outer tank.

EXTERNAL COATINGS:
Each tank is provided with an external protection coating which also acts as corrosion protection, which meets the regulatory specifications.
  • EPOXY-TAR:  protection coating consisting in an epoxy-based, 2-component product made with epoxy resins modified by a coal tar-based ydrocarbon resin.
  • FIBERGLASS (GRP): external treatment based on polyester resins reinforced with fiber-glass material.

INTERNAL COATINGS:
When an internal coating is required, the inner surface is prepared in accordance with the customers’ requirement and the coating manufacturer specifications to ensure permanent adhesion of the selected  coating. On request we can provide the following treatments:
  • Internal coating for non-drinking water: an anticorrosive layer of epoxy-based two-components resin.
  • Internal coating for drinking water: a bicomponent polyammine epoxy coating which is certified for prolonged contact with drinking water and food.
  • Internal coating for aviation fuels: a light coloured epoxy-phenolic resin free from zinc, cadmium and copper alloys.
