Description

It has become traditional that IIAR offer an in-depth examination of selected topics on the Sunday before the Monday start of our annual conference.  For the 2023 conference, we would like to examine aspects of vessel design, inspection and maintenance/repair. Our expected audience would be:

  • Design professionals
  • Contractors
  • End-users
  • Manufacturers packaging or utilizing vessels in the products

There are a number of factors that influence the design of vessels:  capacity, storage, surge, nozzle connections, liquid/vapor separation, baffling and etc.  And then there are the factors that drive the actual construction‚Ķmaterial thickness, standard sheet sizes, head formation, nozzle reinforcement, all driven by the design temperature and MAWP.  When specifying vessels, heat treatment is essential for some heads, and is sometimes a good idea for the entire vessel.  Where corrosion is a possibility, corrosion mitigation or a corrosion allowance is a necessity.  After fabrication, labeling, testing, and certification must be compliant with ASME Rules and listing in the NBIC is essential. Records must also be updated when vessels are repaired, re-rated for temperature and pressure, or modified.  

Once the vessels are placed into service, they must be operated, inspected, and maintained. Initial inspections and ongoing inspections are needed to maintain mechanical integrity. Overpressure protection is essential and should be carefully designed and maintained, too.  Controls are essential and require testing.  Sometimes loads are added or operating parameters are changed which will require that vessels be evaluated.  When deficiencies are identified, a plan to manage these is needed. 

This workshop will provide attendees a greater awareness and knowledge of the complete life cycle of pressure vessels. We expect that the audience will be well served by understanding principles that underpin vessel design, specification, and operational management to ensure proper performance and ongoing safety. RAGAGEP requirements for pressure vessels should be emphasized throughout the workshop.
