Tank Weight Calculator

Calculate empty weight of cylindrical steel tanks and vessels plus weight when filled with liquid.

Inputs

Enter your values below

Tank Diameter*m

Tank Height (shell)*m

Wall Thickness*mm

Material

Liquid Density*kg/m³

Water = 1000, oil ≈ 850-900

Formula

π × diameter × height × thickness × density + π × (diameter ÷ 2)² × height × liquid_density

Result unit: kg

Steel weight: π × D × H × t × ρ (cylindrical shell). Contents weight: π(D/2)² × H × ρ_liquid. Both dimensions in m, thickness in m (converted from mm). Plus two heads ≈ 2 × (πD²/4) × t × ρ.

Introduction

Estimate the weight of a vertical cylindrical steel tank including both the steel shell and its liquid contents. Used for foundation design, lifting calculations, and transport planning. (Simplified — does not include heads, nozzles, or stiffeners.)

Calculation Example

3m × 6m × 8mm carbon steel tank + water: shell ≈ 3,550 kg + water ≈ 42,412 kg = ~46,000 kg.

Inputs: diameter=3, height=6, thickness=8, density=7850, liquid_density=1000

Result: 45946 kg

Engineering Applications

•Foundation loading
•Lift planning
•Transport weight
•Seismic design

Frequently Asked Questions

What about head weight?

Two dished heads add approximately 15-25% to shell weight. For precise weight use pressure vessel design software.

What safety factor for lifting?

Use 1.5× operating weight minimum, plus dynamic factors for crane lifts. Always consult a structural engineer for lifting plans.
