Hemispherical Shape v Torispherical Shape

Global Stainless Industrial HemisphereThe hemispherical shape is superior to the torispherical shape in strength.  Hemispheres are the best shape for mixing vessels such as pharmaceutical manufacturing bowls, because the corner which can cause burning-on of product in a torispherical shape, is therefore eliminated.  Our hemispheres are of extra smooth contour, so that agitator blades swipe the surfaces much more effectively.

Hemispheres offer a stronger vacuum, and drain better as a tank or pressure vessel bottom.  Hemispheres are the well accepted shape for specialist pressure vessel design, notably in the pharmaceutical, cosmetic, and food cooking, industries.
