Elliptical Head

The elliptical head ( or named ellipsoidal head ) which is a head consisting of two parts: a rotating ellipsoidal sphere and a cylindrical straight section.

Elliptical tank head is fabricated to have a certain shape instead of a particular dish radius or knuckle radius. The dish radius is approximately 90% of the diameter and the knuckle radius is approximately 17% of the diameter. 2:1 elliptical flanged and dished heads are ASME compliant.

What should be considered in the selection of the heads?

1. Customer requirements

2. Requirements of Chemical Process

Conical heads are used for vertical vessels of solid masses to facilitate the flow and discharge of masses. Elliptical head or spherical head for liquid masses.

Stirred pressure vessels should determine the shape of the head according to the shape of the slurry leaf and the flow form of the working mass.

3. According to the pressure. For medium and low pressure pressure vessels, ellipsoidal heads are mostly used. For high pressure and ultra-high pressure pressure vessels, spherical heads are mostly used.

4. Determine from the analysis of considering the stress situation. If the stress transition zone of ellipsoidal head is opened with larger openings and the local stress is too large, spherical head can also be considered.
