Pain Points in This Industry
- Torispherical heads leave a corner where product burns on.
- Agitator blades do not sweep a torispherical wall effectively.
- Vacuum performance and draining are limited by head geometry.
- Wall thickness requirements exceed what press tooling can reach.
What Customers Need
- A true hemispherical head, not a torispherical approximation
- An extra smooth contour so blades sweep the full surface
- Heavy wall thickness up to 16mm
- 316 and 316L availability

900mmProcess And Pressure Vessels FAQ
Why choose a hemisphere over a torispherical head?
The hemispherical shape is superior in strength, eliminates the corner that causes product burning-on, lets agitator blades sweep the surface more effectively, holds a stronger vacuum and drains better.
What is the maximum wall thickness?
16mm (5/8 inch) by spinning, in sizes from ∅89mm to ∅3500mm.
Which alloys are available?
AISI 304, AISI 316 and AISI 316L.
Can you supply a specific internal surface finish?
Mirror polished, mill finished, sandblasted and electroplated are standard. Confirm the requirement with your enquiry.
