A dished end is a type of end cap or closure used in pressure vessels, boilers, and storage tanks to enclose one or both ends of the cylindrical shell. It has a concave, rounded shape that resembles a shallow dish, hence the name. Dished ends are designed to handle internal pressure effectively while maintaining structural stability and reducing the risk of stress concentration.

The dished end has a shallow, rounded profile, typically created with a central concave portion and a more steeply curved edge. This shape helps distribute pressure evenly, though not as effectively as elliptical or hemispherical ends.

Dished ends are widely used in pressure vessels, boilers, and storage tanks across industries such as oil and gas, chemical processing, pharmaceuticals, and food and beverage. They are especially common in applications requiring low to moderate pressure containment.

Dished ends are selected based on factors like pressure requirements, material efficiency, and cost, with torispherical and ellipsoidal heads being popular choices due to their balance of performance and affordability.
