REA : CN-135960
Capitale Sociale : 2.000.000 i.v.
Industry: Chemical
Client: Leading company (North-West Italy)
Year of completion: 2024
Objective:
On-site construction of three concentric tanks designed for the biological treatment of industrial wastewater through nitrification and denitrification processes. The project, carried out for a major chemical group, required high-precision work directly on site.
Technical Specifications:
- External diameters: Ø17,200 mm (outer), Ø13,800 mm (intermediate), Ø11,300 mm (inner)
- Height: 11,000 mm
- Thickness: ranging from 5 mm to 12 mm
- Usable volume per tank: 2,300 m³
- Material: Stainless steel AISI 304L
- Internal finish: pickled and passivated
Standards and Design Codes:
- Design code: EN 14015
- Material certification: EN 10204 3.1
- Quality control: VT + PT tests according to EN ISO 9712
- Welding: according to EN ISO 3834-2
- Mechanical tests and inspections: performed on-site under the supervision of the client and a third-party body
Key Strengths:
The three tanks were engineered to fit precisely one inside the other with millimetric accuracy, a complex engineering operation carried out entirely on site. The sequential assembly minimized site footprint and ensured rapid integration into existing systems.
