Design & Geometry
What Are Torispherical Dished Ends?
Torispherical Dished Ends (also known as torispherical heads, flanged dished ends, or Klöpper heads) are pressure-retaining components with an engineered geometry for efficient stress distribution.
A Torispherical End consists of:
-
Crown radius (Rc) – the main spherical portion of the head
-
Knuckle radius (Rk) – the toroidal transition between crown and straight flange
-
Straight flange – the cylindrical section enabling weld joint to the shell
This geometry distributes internal pressure loads more uniformly, reducing peak stresses and offering a strong balance between structural rigidity and cost-effectiveness.
