Torispherical Steel Dished Ends Heads For Heat Exchanger Parts

Product Specification

A516 GR.70 Elliptical Heads Torispherical Heads Tank Caps For Heat Exchanger Parts.

PRODUCT DETELS
 

A516 GR.70 is a common grade of carbon steel that is often used in the fabrication of pressure vessels, including heat exchangers. When it comes to the heads or caps used in heat exchanger parts, both elliptical and torispherical heads can be employed, depending on design requirements.

1. Elliptical Heads:

   • Elliptical heads, as mentioned earlier, have a shape that closely resembles a segment of an ellipsoid.
   • The major radius (R) is typically equal to the inside diameter (ID) of the heat exchanger, while the minor radius (r) is typically 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.
   • These heads are often used in heat exchangers operating at low to medium pressures.

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 heat exchangers operating at medium to high pressures.

When using A516 GR.70 carbon steel for these heads, it is important to follow appropriate material specifications and design guidelines outlined in relevant codes and standards, such as ASME Section VIII, to ensure the pressure vessel's integrity and safety.

It should be noted that the specific choice between elliptical and torispherical heads for heat exchangers will depend on factors such as the design pressure, temperature, and other process conditions. Consulting with a qualified engineer or referring to the appropriate design codes and standards is essential for selecting the most suitable head type for your specific heat exchanger application.
