NEN-EN 14015 Vertical flat-bottomed tanks
The EN 14015 is the European standard for the design and manufacture of vertical, cylindrical, above-ground, welded steel tanks with flat bottoms. The tanks are designed for the storage of liquids at ambient temperature and higher. This norm dictates tank design, manufacture, welding, inspection and installation requirements. These tanks are designed in order to withstand low internal pressures, for the storage of typical products such as crude oil, petrol, chemicals and water. If your installation has to satisfy the PGS 29 directive, then newly-built tanks must comply with EN 14015.
Gpi has extensive experience in the production of EN 14015 tanks, varying from tanks built in the factory up to +/- 500m3, to tanks built on-location up to +/-15,000 m3. Depending on the desired design and design conditions, these tanks are equipped with a conical roof or a doomed roof, with or without anchors and stiffening rings, such as wind girders and/or a top corner ring. Naturally, these tanks can be provided with a spiral staircase, a cage ladder or a stairway. In terms of material, a form of duplex is often chosen. Due to this material being stronger than normal austenitic stainless steel variants, thin walls can be employed, which ensure for a more rapid, higher quality and affordable tank.
Although EN 14015 is primarily meant to apply to tanks manufactured on site, Gpi can also build tanks that conform with EN 14015 in the factory. We do this in our various factories, on the water or by the road. When building on-location, we employ our Coil Building system. Read more about this system here, or watch our Coil Building film.
We also produce tanks according to API 650, the American equivalent of EN14015. Read more about this here.
