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.
