company news about What is an elliptical head?

An elliptical head is a type of end closure widely used in pressure vessels, tanks, and pipelines to seal the ends while withstanding internal or external pressure.

Its key feature is its elliptical shape, where the curved surface transitions smoothly between a semi-elliptical top and a straight cylindrical skirt (the "straight section") that connects to the vessel or pipe. This design allows for efficient distribution of pressure—more uniform than flat heads and more space-efficient than hemispherical heads—making it suitable for medium to high-pressure applications.

Typically made from materials like carbon steel, stainless steel, or alloy steel (depending on the working environment, such as corrosion resistance needs), elliptical heads are formed through processes like stamping or spinning. They are commonly used in industries such as chemical processing, petroleum, food production, and pharmaceuticals, where they balance structural strength, pressure resistance, and practicality.
