Ellipsoidal Heads According to DIN 28013

Ellipsoidal heads, also referred to as Elliptical Heads, are crucial components in the construction of pressure vessels, ensuring durability and functionality. Defined by their characteristic shape and precise engineering, these heads are designed in accordance with DIN 28013 standards, which outline the dimensions and specifications for optimal performance.

Product Overview

Ellipsoidal heads are part of a broader range of vessel components, including:

• Torispherical Heads

• Dished Bottoms for Tank Construction

• Spherical Bottoms

• Flat Bottoms

• Spherical Dished Bottoms

• Dished Discs

• Elliptical Bottoms

• Cones

• Inverted Heads

• Supplementary Equipment

These products cater to diverse industrial requirements, offering a wide selection of solutions for pressure and storage tanks.

Key Features of Ellipsoidal Heads

Ellipsoidal heads combine an elliptical form with a cylindrical straight section, making them both functional and economical. Their 2:1 ratio – where the width of the ellipse is twice the depth – ensures efficiency for medium-pressure applications. Unlike other head shapes, ellipsoidal heads reduce material usage due to their relatively thinner wall thickness requirement while maintaining structural integrity.

Technical Specifications

• External Head Diameter (D₀): Determines the overall size of the head.

• Internal Head Diameter (Dₑ): Accounts for the material thickness.

• Crown Radius (CR): 0.8D₀, defining the curvature of the head’s top.

• Knuckle Radius (KR): 0.154D₀, representing the curvature transition to the straight section.

• Straight Flange Height (SF): Typically 3t or per specific requirements.

• Depth of Dishing (DH): 0.255D₀ – 0.635t, measuring the vertical depth of the elliptical segment.

• Total Internal Head Height (THₑ): Sum of SF and DH.

• Wall Thickness (t): Dictated by pressure and material properties.

Manufacturing Excellence

Ellipsoidal heads are fabricated with advanced techniques to meet precise standards:

1. Materials: High-quality steel and alloys tailored for pressure resistance and durability.

2. Dimensions: Accurate to DIN 28013 for consistency and reliability.

3. Welding and Cutting: High-precision processes ensure seamless joints and smooth finishes.

4. Dishing and Flanging: Critical for shaping and reinforcing structural integrity.

5. Edge Processing: Enhances durability and safety.

6. Heat Treatment: Improves material properties for performance under pressure.

7. Surface Treatment: Adds corrosion resistance and extends product lifespan.

8. Joggling and Nozzle Cut-Outs: Customized options for specific application requirements.

Advantages of Ellipsoidal Heads

• Cost-Effective: Optimized material usage reduces manufacturing costs.

• Durable: Robust design suitable for medium-pressure tanks.

• Efficient Design: The elliptical shape minimizes stress concentrations.

• Versatile Applications: Widely used in industries such as petrochemicals, pharmaceuticals, and food processing.

Conclusion

Ellipsoidal heads according to DIN 28013 are a benchmark in pressure vessel technology. Their innovative design and stringent manufacturing standards make them an excellent choice for applications requiring reliability, efficiency, and safety. By combining advanced engineering with cost-effective solutions, ellipsoidal heads continue to be an indispensable component in modern industrial systems.
