When it comes to heads for steel pressure vessels and boiler heads, there are different types available depending on the specific requirements of the vessel. Let's discuss two specific types: spherical crown heads and large diameter elliptical heads, both made from carbon steel.

1. Spherical Crown Heads:

   • Spherical crown heads, also known as hemispherical heads, have a shape that closely resembles a segment of a sphere.
   • These heads offer excellent structural strength and are often used in high-pressure applications, such as boilers and pressure vessels.
   • Spherical crown heads distribute stress more uniformly, reducing stress concentrations and enhancing the overall integrity of the vessel.
   • They provide smooth transitions and are suitable for applications where pressure vessel heads need to withstand high internal pressures.

2. Large Diameter Elliptical Heads:

   • Large diameter elliptical heads, also known as ellipsoidal heads, have a shape that closely resembles a segment of an ellipsoid.
   • These heads are designed with a larger radius (R) in comparison to standard elliptical heads to accommodate larger vessel diameters.
   • The major radius (R) is typically equal to the inside diameter (ID) of the pressure vessel, while the minor radius (r) is usually 0.9 times the major radius.
   • Large diameter elliptical heads provide smooth transitions, distribute stress more uniformly, and help minimize stress concentrations.
   • They are commonly used in pressure vessels, boilers, and other cylindrical vessels with larger diameters.

Both spherical crown heads and large diameter elliptical heads can be fabricated from carbon steel, which is widely used for its mechanical properties and cost-effectiveness. Carbon steel offers good strength and weldability, making it suitable for pressure vessel applications.

It's important to consider the specific design requirements, such as pressure, temperature, and vessel size, when selecting the appropriate head type. Additionally, adherence to relevant codes and standards, such as ASME Section VIII, Division 1, is essential for ensuring the heads meet the required specifications and safety standards for pressure vessel and boiler applications.

Consulting with a qualified engineer or referring to the applicable design codes and standards will help ensure the correct selection and design of carbon steel spherical crown heads or large diameter elliptical heads for your specific pressure vessel or boiler.
