At Haipei industry, we specialize in manufacturing high-quality elliptical tank heads designed to meet the demands of diverse pressure vessel environments. Our elliptical tank heads are engineered for efficiency, durability, and compliance with stringent industry standards, making them a trusted choice for medium-pressure applications.

Key Design Features

An elliptical tank head is characterized by a depth of dish equal to one-quarter of the internal diameter (ID). When combined with a straight flange, the total inside height is achieved, providing optimal volume and pressure-handling capacity. The 2:1 elliptical flanged and dished design ensures superior structural integrity while maintaining an economical approach to material usage due to reduced metal thickness requirements.

ASME-Compliant Construction
Our 2:1 elliptical tank heads are manufactured in accordance with ASME standards, ensuring reliability and safety. The dish radius is approximately 90% of the diameter, and the knuckle radius is around 17% of the diameter, creating a shape that is both efficient and robust. These heads undergo inspection by ASME Authorized Inspectors to verify compliance, guaranteeing the highest quality for pressure vessel applications.

Advantages of Elliptical Tank Heads

  1. Enhanced Volume Efficiency: Elliptical Heads provide higher internal volume compared to other head shapes of the same diameter, making them ideal for space-optimized designs.

  2. Pressure Compatibility: Suitable for moderate to high-pressure applications, they are widely used in industries like oil, chemical, and power generation.

  3. Material Versatility: Manufactured from various materials, including carbon steel, stainless steel, aluminum, titanium, and duplex steel, they can be customized to meet specific requirements.
