We manufacture elliptical bottoms in two possible variants:


Elliptical bottom 1,9:1
Elliptical bottom

Elliptical bottoms 1,9:1

per NFE 81-103

Di = Do - 2t
CR = Di / 1,16
KR = Di / 5,39

SF = according NFE 81-103
DH = Di / 3,8
THi = SF+DH

Elliptical bottom 2:1
Elliptical bottom

Elliptical bottoms 2:1

per ASME VIII Div. 1.

Di = Do - 2t
CR = 0,9Di
KR = 0,17Di

SF = per request
DH = 0,25Di
THi = SF+DH
