PRODUCT DETELS
 

When it comes to pressure vessel heads, carbon steel is commonly used due to its mechanical properties and cost-effectiveness. There are two types of carbon steel heads that are often used: elliptical heads and torispherical heads.

1. Elliptical Heads:

   • Elliptical heads, also known as ellipsoidal heads, have a shape that closely resembles a segment of an ellipsoid.
   • These heads have two radii: a major radius (R) and a minor radius (r).
   • The major radius is typically equal to the inside diameter (ID) of the pressure vessel, while the minor radius is usually 0.9 times the major radius.
   • Elliptical heads provide smooth transitions and distribute stress more uniformly, making them suitable for applications where stress concentrations need to be minimized.
   • They are commonly used in pressure vessels, tanks, and other cylindrical vessels.

2. Torispherical Heads:

   • Torispherical heads, also known as flanged and dished heads, have a shape that includes a dish portion blended with a smaller radius knuckle.
   • The dish radius (r) is typically 6% of the head's diameter (D), while the knuckle radius (k) is usually 10% of D.
   • Torispherical heads provide good structural strength and are commonly used in pressure vessels, tanks, and other applications.
   • They are suitable for medium to high-pressure applications and are often used when space constraints are a consideration.

In both cases, the specific dimensions of the heads will depend on the design requirements, including pressure, temperature, and vessel size. It is essential to follow the appropriate design codes and standards, such as ASME Section VIII, Division 1, to ensure the heads meet the required specifications and safety standards for pressure vessel applications.

When selecting carbon steel for these heads, considerations such as the carbon content, tensile strength, and impact resistance should be taken into account. The specific carbon steel grade will depend on the application and the applicable codes and standards.

It's important to consult with a qualified engineer or refer to the appropriate design codes and standards to ensure the correct selection and design of carbon steel elliptical heads or torispherical heads for your pressure vessel or tank.
