Dished Only Tank Heads

A Variety of Applications

Dished only tank heads are a simple, cost effective solution. They have no knuckle radius or straight flange, and have a spherical surface like the side of a ball. These heads are used in a variety of applications including pressure vessels, reinforcement pads, domed roofs for large storage tanks, vacuum chambers, wear plates and liners.


Reinforcing Pad

A dished only tank head can be used as a reinforcing pad (re-pad).

Spin Polished

Unlike flanged heads, these heads can be spin-polished for sanitary applications and design.

Atmospheric Storage Tanks Use

Dished only tank heads are ideal for atmospheric storage applications where reduction in evaporation loss is needed.

Heat Treatment

Assembly with heat can be provided, which helps maintain the strength of the metal to meet code requirements and ensure long-lasting performance.


These tank heads are made from: carbon steel, stainless steel, aluminum, and other ferrous and non-ferrous alloys.
