Elliptical Tank Heads: A Cost-Effective Solution for Medium-Pressure Tanks

2:1 elliptical tank heads are an ideal choice for medium-pressure tanks due to their efficient design and reduced metal thickness requirements. These heads offer a cost-effective alternative while maintaining structural integrity.

Specifications

• 2:1 Elliptical Heads

• 120″ OD x 1-1/8″ Minimum Thickness – SA516-70N

• 120″ OD x 3/8″ Minimum Thickness – SA516-70N

Unlike tank heads with a fixed dish or knuckle radius, 2:1 elliptical heads are shaped according to a specific contour. The dish radius is approximately 90% of the internal diameter, while the depth of the head is one-quarter of the vessel’s internal diameter. These features make elliptical heads widely used in pressure vessel applications.

Haipei Industry provides high-speed manufacturing solutions for cold-formed tank heads, segmented umbrella domes, and spherical shroud gores to meet various industry needs.
