High quality torisphere head dish end elliptical head for LPG tank head



When it comes to LPG (liquefied petroleum gas) tank heads, high-quality torispherical heads and elliptical heads are commonly used due to their structural integrity and suitability for pressure vessel applications. Here's some information about these types of heads:

  1. Torispherical Heads:

    • Torispherical heads, also known as flanged and dished heads, are widely used in LPG tank applications.
    • These heads consist of 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 suitable for medium to high-pressure applications.
    • They offer smooth transitions and distribute stress more uniformly, which is important for the safety and integrity of LPG tanks.
  2. Elliptical Heads:

    • Elliptical heads, also known as ellipsoidal heads, are another suitable option for LPG tank heads.
    • These heads 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 LPG tank, while the minor radius (r) is usually 0.9 times the major radius.
    • Elliptical heads provide smooth transitions and distribute stress more uniformly, helping to minimize stress concentrations.
    • They are commonly used in pressure vessels, tanks, and other cylindrical vessels.

For LPG tank heads, it is crucial to prioritize high quality and safety. When selecting torispherical or elliptical heads, consider the following:

  • Choose heads that are manufactured in compliance with relevant codes and standards, such as ASME Section VIII, Division 1, or other applicable regulations.
  • Ensure that the heads are fabricated from materials suitable for LPG service, such as carbon steel or stainless steel, depending on the specific requirements and compatibility with the stored LPG.
  • Work with reputable manufacturers or suppliers with experience in producing high-quality tank heads for LPG applications.
  • Follow proper quality control measures, including inspections and testing, to ensure the heads meet the required specifications and safety standards.

It is recommended to consult with a qualified engineer or refer to the applicable design codes and standards to ensure the appropriate selection and design of torispherical heads or elliptical heads for your specific LPG tank application.
