Elliptical heads are strong, efficient pressure vessel end caps that balance stress distribution, material savings, and compact design.
The ellipsoidal dish end (also called elliptical head) is a critical component for tanks and pressure vessels, made from carbon steel, stainless steel, austenitic, or non-ferritic metals suitable for cold working.
Economical Design: Major-to-minor axis ratio ~2:1, lower height reduces material use.
Customizable: Shape, thickness, material, and diameter tailored to your needs.

Optimized Stress Distribution: Half ellipsoid + cylindrical segment prevents abrupt curvature changes at welds.
Uniform Stress: Smooth meridian curvature distributes stress evenly.
Easier Forming: Shallower depth than hemispherical heads simplifies punching and manufacturing.
