Nozzle Calculator Pro

Nozzle Calculator is a professional engineering and fabrication tool for calculating nozzle orientation and marking dimensions for pressure vessels, cylindrical shells, storage tanks, and dish ends.

The app helps mechanical engineers, pressure vessel designers, fabrication engineers, QA/QC professionals, inspectors, and workshop technicians calculate accurate dimensions required for nozzle positioning, orientation, layout marking, and fabrication inspection.

It eliminates repetitive manual calculations and provides quick, clear, and workshop-ready results.

Included Calculators

• Shell Nozzle Orientation Calculator
• Dish Nozzle Orientation Calculator

Shell Nozzle Orientation

Calculate nozzle marking dimensions on cylindrical pressure vessel shells and tanks.

The calculator determines:

• Shell Outside Diameter (OD) from OCF
• OCF per Degree
• OCF for a Selected Nozzle Angle
• Nozzle Orientation Marking Dimensions

These calculations are useful when transferring nozzle orientation information onto cylindrical shells during fabrication and inspection.

Dish Nozzle Orientation

Calculate nozzle arc distance and orientation dimensions on pressure vessel dish ends.

The calculator supports common pressure vessel head geometries:

• 10% Torispherical Head
• 2:1 Ellipsoidal Head
• Hemispherical Head

Enter the required dish geometry and nozzle orientation information to obtain the calculated arc distance and related marking dimensions.
