ABOUT MULTI SECTIONAL HEADS

[yigithan]

Hı everyone
I have a question for all of you
For a pressure vessel wihich is manufactured and designed acc. to EN13445 and diameter is 3.2mt. Is that any rule for torispherical end for manucaftured multi section ? For exaple can manufactuerer fabricate the head with 15 pieces of sheet ?

A person would have to read EN13445 to know for sure (I have no copy of same), but I'd be surprised if multi-piece heads were not allowed.

Regards,

Mike

The problem with sloppy work is that the supply FAR EXCEEDS the demand

You can fabricate with two or more parts, but 15 parts is excessive in this case.
EN 13445-4 Fabrication
9.2.5 Forming of Segments
The following equation (9.2-5) shall be used for the calculation of deformation F of segments e.g. of multi-sectional
torispherical heads or spheres (see also Figure 9.2-5.
