Norms and standards

ASME SECTION VIII division 1 – is the classic American Pressure Vessel Standard for general applications. This standard, always considered in Sant’Ambrogio Pressure Vessel software, is available in the NEXTGEN suite of programs, which includes specific modules for the structural calculation of columns under wind and seismic loads, for the calculation of vessels of rectangular section according to Appendix 13 and of clamp connections according to Appendix 24 of ASME VIII div.1 ►

ASME SECTION VIII division 2 – is the advanced American Pressure Vessel Standard generally used in pressure vessels and heat exchangers with critical design conditions, or where a Design by Analysis or a Fatigue Analysis is required. This standard is available in the NEXTGEN suite of programs, which includes specific modules for the structural calculation of columns under wind and seismic loads to ASME VIII div.2 and for the calculation of clamp connections according to Chapter 4.17 of ASME VIII div.2 ►

EN 13445 part 3 – is the harmonized European Standard for Unfired Pressure Vessel calculations. It is available in the NEXTGEN suite of programs, which includes specific modules for the structural calculation of columns under wind and seismic loads to EN 13445, for the flange calculation according to Clause 11 of EN 13445 or according to EN 1591, for the calculation of flanged connections to Appendix G of EN 13445, for the calculation of tubesheets either to Clause 13 or to the alternative method of Annex J, for the calculation of vessels of rectangular section according to Clause 15 of EN 13445 etc. ►
