The safety factor of a pressure vessel is related to both the tensile stress and yield strength for material allowance. ASME code section VIII has fully covered these two on the construction code for pressure vessel. This code section addressed mandatory and non-mandatory appendixes requirement, specific prohibition, vessel materials, design, fabrication, examination, inspection, testing, certification, and pressure relief.

Mechanical design of a horizontal pressure vessel based on this standard had been done incorporating PV ELITE software. Analyses were carried out on head, shell, nozzle and saddle. The input parameters are type of material, pressure, temperature, diameter, and corrosion allowance. Analysis performed the calculations of internal and external pressure, weight of the element, allowable stresses, vessel longitudinal stress check, nozzle check and saddle check.

ASME section VIII deals with the design for pressure vessels, materials specification, fabrication, opening and reinforcement, testing and marking, inspection and other mandatory or non mandatory appendixes. Section VIII contains three divisions, covering the different pressure ranges:


  • Division 1: up to 3000 psi (200 bar)

  • Division 2: up to 10000 psi (690 bar)

  • Division 3: above 10000 psi (above 690 bar )


ASME section VIII, Division 1, deals with

conventional pressure vessels means design by rule, while division 2, deals with stringent alternative rules means design by analysis, and division 3 deals with design of Nuclear Equipment.
