Custom Forged Elliptical Hemisphere Spherical Dished Head For Tank Head end


PRODUCT DETELS

When it comes to custom forged tank head ends, both elliptical hemisphere and spherical dished heads can be manufactured to meet specific requirements. Here's some information about these custom forged tank head options:

  1. Elliptical Hemisphere Heads:

    • Elliptical hemisphere heads are formed by cutting an ellipsoid in half along its major axis.
    • These heads have a shape that closely resembles half of an ellipsoid.
    • The major radius (R) is typically equal to the inside diameter (ID) of the tank, while the minor radius (r) is usually half of the major radius.
    • Elliptical hemisphere heads provide smooth transitions and distribute stress more uniformly, making them suitable for applications where stress concentrations need to be minimized.
  2. Spherical Dished Heads:

    • Spherical dished heads, also known as hemispherical heads, have a shape that closely resembles a segment of a sphere.
    • These heads are formed by forging or pressing a flat plate into a curved shape.
    • The radius of the spherical dished head is typically equal to the tank's inside diameter (ID).
    • Spherical dished heads provide excellent structural strength and are often used in high-pressure applications.

Custom forged tank head ends offer flexibility in terms of size, material, and shape. Here are some considerations for customization:

  • Size Customization: The dimensions of the tank head, such as the radius and thickness, can be customized to meet the specific tank requirements.
  • Material Selection: The choice of material will depend on factors such as the operating conditions, compatibility with the process fluid, and required mechanical properties. Common materials for tank heads include carbon steel, stainless steel, and other alloys suitable for pressure vessel applications.
  • Forging Process: Custom forged tank heads are typically manufactured through forging processes that involve heating the material and shaping it using dies and presses. The forging process allows for precise control and customization of the tank head shape.
  • Quality Control: Quality control measures, including dimensional checks, visual inspections, and non-destructive testing, should be carried out during the manufacturing process to ensure compliance with the required specifications and standards.

It is important to work with experienced manufacturers or suppliers who specialize in custom forging of tank head ends. They should have expertise in materials, forging processes, and quality control to ensure the production of high-quality, custom tank heads that meet your specific requirements.
