II) Dished discs, segmental plates for hemispherical ends and spherical tanks
Max. thickness 80 mm
No limitation on diameter
III) Dished and flanged ends manufactured in sections
Max. plate thickness 60 mm
Manufacturing in sections is best applied to large ends where R2 is bigger than 950 mm. The largest end manufactured so far is 46,8 meters in diameter.
A good alternative for ends manufactured in sections is a hemispherical end, as tooling costs are much lower.
