1. Spherical Head: Formed by welding or bolting two hemispherical sections, resembling a complete sphere.Applications: High-pressure vessels such as storage tanks and reactors.

2. Hemispherical Head: Made from a single hemispherical component.Applications: Storage tanks, heat exchangers, and pressure vessels.

3. Flat Head: Fabricated from a flat circular plate.Applications: Low-pressure vessels where simplicity and cost-efficiency are prioritized.

4. Elliptical Head: Features an elliptical cross-section for optimized stress distribution.Applications: Storage tanks and pressure vessels in petroleum and chemical industries.

5. Conical Head: Designed with a conical shape for efficient material flow.Applications: Powder storage and conveying systems.

6. Torispherical Head: Combines a spherical crown with a toroidal knuckle for transitional geometry.Applications: High-pressure vessels and heat exchangers requiring balanced performance.
