Pressure Vessel Heads Pro

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.
