New in ASME VIII-2: Class 1 Vessels

The recently introduced ASME VIII-2 Class 1 designation provides a way to specify and build vessels that are more economical than those produced using traditional Division 1 rules.

Advantages of Class 1 over Division 1 include:

  • Modern, more accurate design equations

  • Higher allowable stresses

  • Reduced wall thicknesses, nozzle reinforcement and welding

Class 1 engineering and documentation requirements are similar to those of Division 1. This means that Class 1 labor and material savings do not come at the expense of additional overheads as is often the case with full Division 2 vessels.
