Haipei Industry SA516 Gr. 70 Carbon Steel With SS316L-Clad Dished Heads

 Haipei Industry SA516 Gr. 70 Carbon Steel With SS316L-Clad Dished Heads 

The elliptical head, also known as the ellipsoidal head, is a highly versatile and reliable component in various industrial applications. Its innovative design combines functionality with compliance to ensure optimal performance across a wide range of industries.

What Are Elliptical Heads?

Elliptical heads consist of two key sections: a rotating ellipsoidal sphere and a cylindrical straight section. Unlike heads with a specific dish radius or knuckle radius, elliptical heads are crafted with precise proportions to achieve their distinctive shape. The dish radius is approximately 90% of the diameter, and the knuckle radius is about 17% of the diameter. These proportions are not only mathematically elegant but also engineered for compliance with ASME standards, particularly the widely used 2:1 elliptical flanged and dished heads.

Key Specifications of Elliptical Heads

• Product Names: Elliptical Heads, elliptical head price, boiler elliptical end cap.

• Diameter: Ranges from 90 mm to 5000 mm, with customizable options.

• Thickness: Between 2 mm and 200 mm, ensuring flexibility for various applications.

• Reduction Ratio (R): About 10%.

• Materials: Available in carbon steel, stainless steel, aluminum, copper, titanium, nickel, and nickel alloy steel.

• Certification: ISO 9001:2015 certified.

• Applications: Commonly used in pressure vessels, heat exchangers, and tanks.

• Manufacturing Technologies: Includes both cold pressing and hot pressing methods.

• Surface Treatment Options: Pickling, sandblasting, or as per customer requirements.

• Packaging: Delivered in secure wooden boxes or iron shelves, or customized packaging as needed.

• Delivery Time: Approximately 30 days.

Ellipsoidal dish end (also called elliptical head or elliptical dish end) is usually made with Carbon steel, stainless steel, austenitic and non ferritic metals that can be cold worked. The elliptical dish end radius varies between the major and minor axis usually with the ratio is 2:1. The shape of this ellipsoidal head is more economical, because the height of the head is just a fraction of the diameter. Our tank head can be customized according to your needs. We can choose the most suitable model for you depending on your demands on shape, thickness, material and diameter.

 Elliptical head is composed of half ellipsoid and a cylindrical straight segments. The Straight section can avoid mutation of radius of curvature between the connection welds of the head and cylinder, thus improving the stress status of the welds.

- As The Meridian curvature change of ellipsoidal part of the tank head is smooth and continuous, the stress distribute uniformly.
- Easy to punch forming compared with the hemispherical head, because the depth of ellipsoidal head is smaller than the hemispherical head. (elliptical end cap)

Applications Across Industries

Material Options

Elliptical heads can be manufactured from various materials to meet specific needs:

• Carbon Steel: Ideal for cost-effective durability (e.g., SA516 GR60N, GR70N).

• Stainless Steel: Provides superior corrosion resistance (e.g., SA240 304, 316).

• Titanium Alloys: Lightweight and highly resistant to extreme conditions (e.g., SB256 GR1, GR2, GR5).

Quality Assurance

Every elliptical head undergoes stringent quality control, including:

1. Physical and chemical material tests.

2. Hot forging and forming.

3. Heat treatment for enhanced durability.

4. Detailed inspections at each production stage.

5. Final finishing, marking, and packing.

Choosing the Right Head

When selecting an elliptical head, consider the following:

1. Customer Requirements: Ensure the design aligns with operational goals.

2. Chemical Process Needs: For liquid masses, elliptical heads or spherical heads are optimal; conical heads are better for solid masses.

3. Pressure Levels: Elliptical heads are ideal for medium to low-pressure applications, while spherical heads are recommended for high-pressure scenarios.

4. Stress Analysis: Assess the stress transition zones and local stress levels to determine the most suitable head type.

Conclusion

The elliptical head is an indispensable solution for various industrial and engineering needs. With its precision design, material flexibility, and compliance with global standards, it offers unparalleled performance and reliability. Whether you’re dealing with pressure vessels, boilers, or heat exchangers, elliptical heads are the perfect choice to meet your needs.
