Manufacturing standards

These bottoms are manufactured in accordance with DIN28011. Manufacturing tolerances strictly follow the DIN28011, highlighting the tolerances on its height, its thickness after forming.

For a tank bottom ordered at a nominal thickness (also called starting thickness) E, the actual thickness measured after forming may differ from E, not only because of the tolerances on the thickness of the sheet, but also because of changes caused by the forming process.

Dished head manufacturing processes

Dished heads are manufactured by cold processes, spinning or press-forming.

All our dished stainless steel are supplied without grease. No heat treatment is performed after forming.

The 900mm diameter bottom with a 4mm thickness is made from a disc without weld.
