Understanding Dished Heads for Tanks

Dished heads, or pressure vessel heads, play a crucial role in tank design by providing end closures that sustain internal pressures efficiently. The choice of head type affects the overall strength, stress distribution, and suitability of the tank for different applications. Below, we introduce the four most common types of dished heads used in pressure vessels.

1. Elliptical Heads (2:1 Elliptical Heads)

Characteristics:

• Feature an elliptical shape with a 2:1 aspect ratio, meaning the major axis is twice the length of the minor axis.

• Provide smooth stress transition from the tank body, reducing stress concentrations and improving durability.

• Offer excellent structural integrity, making them ideal for high-pressure environments.

Applications:

• Used extensively in petrochemical, oil and gas, and power generation industries.

• Commonly found in boilers, storage tanks, and heat exchangers.

2. Hemispherical Heads

Characteristics:

• Resemble half of a sphere, ensuring uniform curvature and superior stress distribution.

• Offer the highest strength among head types, making them suitable for extreme pressure conditions.

• Provide optimal volume-to-surface area ratio, improving efficiency in high-pressure containment.

Applications:

• Commonly used in high-pressure gas storage tanks, industrial autoclaves, and nuclear reactors.

3. Torispherical Heads (ASME F&D Heads)

Characteristics:

• Feature a spherical crown with a conical knuckle, creating a slightly flattened spherical shape.

• Deliver good stress distribution and structural strength.

• The knuckle radius can be customized to meet specific design requirements.

Applications:

• Widely utilized in chemical processing, food and beverage, and pharmaceutical industries.

• Ideal for medium to high-pressure applications such as storage tanks, distillation columns, and reactors.

4. Flat Heads (Dished Heads)

Characteristics:

• Consist of a simple flat plate design, making them cost-effective and easy to manufacture.

• Best suited for low-pressure or atmospheric tanks due to their limited pressure containment capability.

• Provide straightforward installation and fabrication, ideal for certain storage applications.

Applications:

• Typically used in low-pressure or non-pressurized storage tanks.

• Found in applications where cost and ease of manufacturing take precedence.

FAQ

Q: What’s the information should I provide when inquiry?

A: Thanks for your question. If you have drawings, we will be entirely in accordance with production drawings . If you do not have the drawing, you can tell me the product data. There are several important data, such as material, type of head( We have elliptical head, hemispherical head, dished head, flat head, etc. ),diameter, thickness, special tolerances or requirements. We can do the drawings according to your requirements, and you confirm that the final product drawings.

Q: what are surface treatment of the product?

A:Thanks for your question. For carbon steel products, we sandblasting descaling product surface. For stainless steel products, we use acid to remove surface oil and impurities.

Q: How do you ensure the quality of products?

A: Thanks for your question.Our production staff is trained through national quality department, and obtain the corresponding certificate, with years of production and design experience. Weld must undergo X-ray inspection to ensure that no defects.
