The Engineering Department of IIS SERVICE is involved in the design and calculation for pressure vessels. In several contexts, from the sizing calculation to the life extension evaluation, from the assessment for equipment operating in the creep range, to the fatigue life evaluation, and, at last, where FFS (Fitness For Service) and ECA (Engineering Critical Analysis) assessments are required, the following activities may be carried out:

  • Design "by formula" of pressure vessels in compliance with
    ISPESL VSR/VSG codes;
  • Design "by formula" of pressure vessels in compliance with
    ASME Boiler & Pressure Vessel Code;
  • Design "by analysis" of pressure vessels in compliance with
    ASME B&PV Code, Sec. VIII, Div. 2, Part 5;
  • Design "by analysis" of pressure vessels in compliance with
    EN 13445, Part 3, Annex B & C;
  • Assessment of fatigue life for pressure vessels in compliance with
    EN 13445, Part 3, Chapter 17 & 18;
  • Minimum Pressurizing Temperature (MPT) evaluation with reference to the start up phase for process plants.

Scenarios

Buckling assessment

In the design of equipment in pressure, in some cases, it is necessary to verify the components resistance against equilibrium instability phenomena ("buckling"): this is...
