UNDERGROUND DOUBLE WALL TANKS

 

Destination – the storage of flammable, caustic or toxic liquids.

Quality and safety

 

The latest technologies for the production of tanks based on years of experience and qualifications of the staff engaged in the production process from the engineering department, through logistics, quality control and production, ensure the finest quality of tanks and the safety of storing harmful and hazardous substances for humans and environment.

Design and manufacture under the control of notified bodies

 

The technical documentation of tanks, production processes and the final acceptance of tanks manufactured by EKONSTAL are agreed, accepted and approved by the Office of Technical Inspection (UDT) as well as other notified bodies. Our tanks hold certificates of approval issued by offices like the Chief Office for Measurements (GUM) to ensure that they comply with the applicable requirements of metrology standards.

Technical characteristics

Made in accordance with EN 12285-1, DIN 6608 or WUDT/UC/2003 Material – certified carbon steel S235JR. Preparation of the external surface of tank sheets – grit blasting with the cleanliness degree of Sa 2.5 according to PN-ISO 8501-1. Polyurethane topcoat ENDOPRENE ensuring resistance to electric breakdown up to 14kV. Tanks can be provided with the additional internal surface security by using special paints resistant to substances stored in the tank. Depending on the option, tanks are adapted to wet, dry, vacuum and excessive interstitial space control method.
