Pressure Vessel Heads Calculator is a professional engineering and fabrication tool for calculating dimensions, blank diameter, weight, radii, and height of commonly used pressure vessel heads and dish ends. Designed for pressure vessel fabricators, mechanical engineers, manufacturing professionals, workshop technicians, estimators, QA/QC engineers, and students, the app provides fast and convenient calculations for pressure vessel head fabrication and material planning. Supported Pressure Vessel Heads • Flat Heads / Flat Dish Ends • Torispherical Heads / F&D Dish Ends • 2:1 Ellipsoidal Heads • Hemispherical Heads • Ellipsoidal Head Template Layout What You Can Calculate Depending on the selected head type, the app can calculate: • Blank Diameter • Head Height • Crown Radius • Knuckle Radius • Straight Face • Inside Diameter • Developed Dimensions • Head Weight • Material Weight Flat Head Calculator Calculate the required blank diameter, head height, and weight using the required dimensional and material inputs. 2:1 Ellipsoidal Head Calculator Calculate important head dimensions including crown radius, knuckle radius, height, blank diameter, and weight. The calculation can also account for straight face dimensions where applicable. Torispherical / F&D Head Calculator Calculate crown radius, knuckle radius, head height, blank diameter, and estimated weight for torispherical pressure vessel heads. Hemispherical Head Calculator Calculate radius, height, blank diameter, and weight for hemispherical pressure vessel heads. Ellipsoidal Head Template Layout Generate template layout marking information for ellipsoidal heads to assist with plate marking, cutting, fabrication, and forming operations. Material Weight Calculation Estimate head weight using material density. Select from commonly used materials or enter a custom material density for your specific application. Supported material options include: • Carbon Steel • Stainless Steel • Aluminium • Brass • Bronze • Copper • Lead • Custom Material Features • Fast engineering calculations • Fabrication-friendly results • Metric and Imperial units • Dimensions in mm or inches • Material density selection • Custom material density support • Clear input and output information • Visual input guidance • Template layout calculation • Simple and easy-to-use interface • No internet connection required • No distracting advertisements Designed For Pressure Vessel Fabrication, Boiler Manufacturing, Heat Exchanger Fabrication, Storage Tank Manufacturing, Process Equipment, Mechanical Engineering, Industrial Fabrication, Material Estimation, Costing, QA/QC Inspection, Workshop Engineering, and On-Site Engineering. Pressure Vessel Heads Calculator helps reduce manual calculations, save fabrication time, improve material estimation, and provide convenient dimensional information for pressure vessel head and dish end fabrication. Whether you are calculating a flat head, F&D head, 2:1 ellipsoidal head, hemispherical head, or developing an ellipsoidal head template, this app provides a convenient engineering tool for fabrication and workshop applications. ## Key features - Calculate blank diameter - Calculate crown radius - Calculate knuckle radius - Calculate height (with/without SF) - Supports flat, torispherical, ellipsoidal, and hemispherical heads - 2:1 ellipsoidal head template layout marking - Customizable layout part divisions ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/pressure-vessel-heads-pro/id1486607999/reviews.md ### 1/5 — O app não funciona | The app doesn't work *2024-04-16* Comprei, baixei e intalei o app, porém ele não executa, tanto no iOS, iPadOS e no macOS. I bought, downloaded and installed the app, but it doesn't run on any iOS/iPadOS/macOS. Se pudesse cancelar a compra eu faria. If I could cancel the purchase, I would do it. Não recomedo!!! I don't recommend it!!! ### 1/5 — Can’t read all dimensions *2020-11-20* When you’re looking at the bottom for the dimensions.... it’s cut off and you can’t get accurate numbers for the heads. I feel like that’s a big design flaw. ## Frequently asked questions about Pressure Vessel Heads Pro ### What types of vessel heads can Pressure Vessel Heads Pro calculate?
