CARBON STEEL TANKS
We design and manufacture carbon steel tanks with capacities from 1 to 200 m³ for storage of water, fuels, chemicals, digestate / wastewater and various process media. Configurations can be vertical or horizontal, installed on support legs or a structural frame. On request we supply thermal insulation, heating/cooling jacket, agitators and process connections according to the P&ID specification. The tank design and coating system are adapted to the medium and environmental conditions.
Each tank is delivered with complete technical documentation: material certificates EN 10204 3.1, welding log and test reports. Welded joints are examined by NDT methods (VT/MT or PT on request), and the shell is subjected to hydrostatic pressure testing. For internal linings we also perform holiday testing (coating porosity detection) when required.

FREQUENTLY ASKED QUESTIONS – CARBON STEEL TANKS
The standard range is 1–200 m³. Dimensions (diameter/height or length/diameter), vertical or horizontal orientation and type of supports (legs/frame) are adapted to the available space and process. Larger capacities are possible on request.
We typically use S235JR / S355 (EN 10025) for atmospheric tanks and P265GH / P355GH (EN 10028) where elevated temperatures/pressures are expected. The final selection depends on the stored medium, operating temperature and tank design.
Yes. Surface preparation is performed by blasting to Sa 2.5, followed by multi-layer coating systems (for example zinc-rich primer / epoxy intermediate coat / polyurethane topcoat). Internal linings are epoxy or chemical-resistant systems selected according to the process medium. We keep detailed DFT records and, when required, perform holiday testing of the internal coating.
