Spheres and Hemispheres
Global Stainless Industrial are specialist fabricators of metal spheres and hemispheres. They are fabricated in various thicknesses and material types for diverse uses including duplex stainless steel pressure vessels, pharmaceutical vessels, vacuum tanks, manure spreader tanks, plastic moulds, cement silo ends, marine buoys, dome bottom silos and air receivers.
Global Stainless manufacture spheres and hemispheres custom made to your requirements, and can offer ASME VIII and AS1210 certification. All products are quality inspected in our workshop prior to dispatch, typically including ultrasound thickness testing, dimensional checks and verification reports by SGS M&I.
Hemispherical Shape v Torispherical Shape
The 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.
