Petal Layout Pro
Sphere & Head Development
$3.99 · Designed for iPad. Not verified for macOS.
Generate accurate petal layout dimensions for spheres and hemispherical heads with multiple development divisions for pressure vessel and tank fabrication.
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
