Dished-only heads are made so that the piece of metal takes shape like a contact lens. This style of tank head has no knuckle radius or straight flange. Dished-only tank heads are a simple, cost-effective solution for vacuum chambers, pressure vessel reinforcement, and storage tank roofs.

Defining Features

• Can be used as a reinforcing pad (re-pad)
