Dished head thicknesses

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.

This dished head is made from a disc without weld.

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.

316L - 1.4404 stainless steel

This dished head is made from a sheet of stainless steel 316L - 1.4404 in 8 mm thickness.

The 316 stainless steel contains molybdenum, which gives it a high resistance to corrosion (especially chlorine and sea water).

The origin of stainless steel sheets (selected for the manufacture of heads) is European, and each manufacturer is ISO-9001 certified.
