Hi! everybody
Hope you all are doing well.
I was performing annular plate width design and as per API 650 Clause E.6.2.1.1.2 Annular Ring Requirements point no.3) When the bottom plate under the shell is thicker than the remainder of the tank bottom, the minimum projection,
L, of the supplied thicker annular ring inside the tank wall shall be the greater of 0.45 m (1.5 ft) or as determined
in equation (E.6.2.1.1.2-1); however, L need not be greater than 0.035 D:
My question is that L = MIN 450 mm is cited in API why it should not be greater than 0.035 D because my D=8m which gives L= 280mm then what should i consider 450 Or 280?
