You are looking for an analytical method able describe nozzle deflections/rotations and allowable loads. Now you have a 'small'â€ tank out of API 650 scope and out- anyway- of scope of Appendix P2. 1 Stoomwezen Regelwerk Rules of Pressure Vessels (RTOD) Welding.

The boundary conditions for the analysis shall assume a fully plastic moment caused by yielding of the plate beneath the shell and zero radial growth.' We calculate by AD 2000 - Rules EN 13445 British Standard ASME Code Sect.

'For tanks where L/H is greater than 1000/6 (2 in US Customary units), the selection of shell thicknesses shall be based on an elastic analysis that shows the calculated circumferential shell stresses to be below the allowable stresses given in Tables 5-2a and 5-2b. En 14015 Calculation Update This RP Now, our friends at the API described in their RP 2000 (about 10 years ago) a way to calculate the flowrate of thermal inbreathing. You may compare this assumption with the 'modern' assumption as in API 650, 5.6.5 Calculation of Thickness by Elastic Analysis One reason is due to the fact the equations the authors used for calculating tank shell deflection and rotations assume that the bottom to shell joint behaves as a hinged connections. This appendix is intended to be used for tanks larger than 36 m (120 ft) in diameter, and only when specified by the Purchaser for tanks 36 m (120 ft) in diameter and smaller. Appendix P, P2 method is based on two articles by Billimoria and Hagstrom/ Billimoria and Tam.
