Haipei Industry Co., Ltd.
Haipei Industry Ellipsoidal Dish End Elliptical Head

HAIPEIINDUSTRY Ellipsoidal Dish End (Elliptical Head)
Product Overview
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.
Key Features
-
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.
