Latest company case about Spherical Heads

ASME stainless steel ellipsoidal heads, also known as elliptical heads, are commonly used in the construction of tanks and pressure vessels. These heads are shaped like a section of an ellipsoid, which is a three-dimensional curved surface resembling a flattened sphere.

Elliptical heads offer several advantages in tank construction, including:

  1. Pressure Resistance: The curved shape of the ellipsoidal head provides inherent strength and resistance to pressure. This makes them suitable for containing fluids or gases under high pressure.

  2. Efficient Use of Material: Ellipsoidal heads distribute internal pressure more evenly throughout the surface, resulting in a more efficient use of material compared to other head shapes. This can lead to cost savings in material and manufacturing.

  3. Smooth Transition: The transition between the head and the cylindrical portion of the tank is smooth, reducing stress concentrations and enhancing structural integrity.

  4. Aesthetic Appeal: Ellipsoidal heads provide a visually pleasing appearance, commonly used in industries where aesthetics are important, such as architectural or decorative applications.

When selecting ASME stainless steel ellipsoidal heads for tanks, it is crucial to consider factors such as the material grade, thickness, pressure rating, and dimensional specifications. Compliance with relevant standards, such as those set by the American Society of Mechanical Engineers (ASME), is essential to ensure the heads meet the required safety and performance criteria.


Consulting with experienced engineers or manufacturers specializing in tank construction and pressure vessel components is recommended to ensure the proper selection and fabrication of ASME stainless steel ellipsoidal heads for your specific tank application.
