Semi Ellipsoidal & Torispherical Dished Ends


As specialised components used in the manufacture of pressure vessels, storage tanks, and process vessels, semi-ellipsoidal and torispherical hot-pressed code dished ends are integral in many industries.

The distinct hot-pressing process used to create their specific curvature allows them to develop a semi-ellipsoidal or torispherical shape, each with unique benefits. Although the result may differ, the technique involved is the same. The steel is shaped within the materials normalising temperature range, ensuring strength and structural integrity.




Comparing Dished Ends


Semi-ellipsoidal and torispherical hot-pressed code dished ends have distinct differences in shape, curvature, and stress distribution characteristics. 


Semi-Ellipsoidal Dished Ends


The semi-elliptical dished and flanged ends feature a shape similar to a section of an ellipsoid. However, the more pronounced profile makes them unique from their torispherical counterparts. The curvature means they’re suitable for applications that require this shape, and higher working pressure due to their deeper head depth.


Torispherical Dished Ends


A torispherical dished and flanged end has a shallower profile than a semi-ellipsoidal end. Characterised by a smoother and less pronounced curvature, they’re ideal for applications where limited space is a factor. They’re also more affordable to produce, adding economical benefits.



Common Applications for Dished Ends


Semi-ellipsoidal and torispherical hot-pressed code dished ends are used in numerous industries and applications, particularly in the manufacture of pressure vessels, storage tanks, and process vessels. Likewise, torispherical and semi-elliptical ends are too.

Their ability to strengthen the structural integrity and guarantee the safe containment of pressurised materials makes them a vital element in many industries. And some of the most common sectors that use them are:

  • Petrochemical and chemical
  • Power generation
  • Water treatment
  • Offshore operations
