DesignCalcs now supports a basic ASME Section VIII, Division 2 nozzle design.  Currently this supports a radial, abutting groove configuration that is straight barrel with no repad in a cylindrical host.  The calculations covered include the Pressure Area method, Weld Strength, Weld detail, Service Thickness checks, and Nozzle rupture checks for pressure loads

Nozzles are openings in cylindrical shells.  The nozzle methodology comes from the following ASME Section VIII, Division 2 paragraphs:

  • 4.1.2 (Minimum Thickness Requirements)
  • 4.2 (Weld Joint Efficiency)
  • 4.5.2 (Dimensions and Shapes of Nozzles)
  • 4.5.4 (Nozzle Neck Minimum Thickness Requirements)
  • 4.5.5 (Radial Nozzle in a Cylindrical Shell)
  • 4.5.14 (Strength of Nozzle Attachment Welds)
