Petal Layout Pro

Petal Layout is a professional fabrication calculator for developing petal-type layouts for spheres and hemispherical heads. It is designed for pressure vessel fabrication, process equipment manufacturing, spherical tank fabrication, and industrial sheet metal work.

The app generates fabrication-ready layout dimensions that can be used for marking plates or sheet metal before cutting, forming, and assembling spherical or hemispherical components.

Whether you are a fabrication engineer, fitter, workshop technician, production engineer, or pressure vessel professional, Petal Layout helps simplify complex petal development calculations and improves accuracy during fabrication.

Supported Petal Layouts

• Hemispherical Head / Hemi Head
• Hemispherical Dish End
• Sphere / Spherical Tank

Hemispherical Head Petal Layout

Generate petal development dimensions for hemispherical pressure vessel heads and dish ends.

Enter the required head diameter and straight face length, select the desired number of development divisions, and calculate the layout dimensions required for plate marking.

Sphere Petal Layout

Generate petal-type development dimensions for spherical tanks and spherical shells.

Enter the sphere diameter and select the required number of divisions to generate the layout dimensions for fabrication.
