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. Development Options Choose from predefined development divisions: • 12 Parts • 24 Parts • 36 Parts • 48 Parts You can also enter a custom number of development divisions according to your fabrication requirements. Features • Sphere petal layout development • Hemispherical head petal development • Dish end petal layout • Spherical tank layout calculations • Multiple development division options • Custom development line/part count • Fabrication-ready marking dimensions • Clear and easy-to-understand results • Simple professional interface • Metric and Imperial unit support • No internet connection required Fabrication Applications Petal Layout is useful for: • Pressure Vessel Fabrication • Spherical Tank Fabrication • Process Equipment Fabrication • Storage Tank Manufacturing • Dish End Fabrication • Hemispherical Head Fabrication • Sheet Metal Fabrication • Industrial Fabrication • Plate Layout and Marking Designed For • Fabrication Engineers • Fabrication Fitters • Production Engineers • Mechanical Engineers • Workshop Technicians • Pressure Vessel Fabricators • Tank Fabricators • Process Equipment Manufacturers • Fabrication Supervisors • Engineering Students For improved fabrication accuracy, the app can be used with appropriate mean dimensions when developing and marking petal layouts.
