Thin walls, precise geometry

Manufacturing and installation of a 10-tonne stainless steel hot water tank

Heat exchangers
Food industry
Hungary

We manufactured a 150 m³ atmospheric hot water tank from 1.4301 stainless steel, then delivered and commissioned it in Kisvárda. The tank has a vertical cylindrical design with a flat bottom and conical roof, and is equipped with an insulation support ring. However, it does not fall under the scope of the Pressure Equipment Directive (PED).

Key technical data

  • Volume: 150 m³
  • Diameter: 4,500 mm
  • Total height, including platform and ladder: 12,200 mm
  • Weight: 10 tonnes

Technical challenges

The main technical challenge in manufacturing was the 5 and 6 mm wall thickness: at this scale, it carries a real risk of permanent deformation. We addressed this with two methods used in parallel: additional hollow-section stiffeners were applied during assembly, while reinforcement rings were welded onto the outer surface of the shell. This ensured geometric accuracy throughout the manufacturing process, transport and lifting into position.

The completed tank was delivered to Kisvárda and lifted into place by crane. Lifting it into position required precise technical preparation and closely coordinated execution.

Precision at every stage – from the first weld to the final lift.
