This tool helps engineers and fabricators estimate the weight of formed dish ends used in tanks, reactors and pressure vessels. It gives a quick result for blank diameter, developed area and approximate material weight.

Dish ends are common in industrial fabrication because they close cylindrical shells safely and efficiently. Different shapes are used based on pressure, cost and forming method. Torispherical ends are common for general fabrication. Ellipsoidal ends are useful for better pressure performance. Hemispherical ends are used where higher pressure strength is required.

Common Dish End Types

The most used dish end types include torispherical, ellipsoidal, hemispherical and flat circular ends. Each type has a different developed shape. Therefore, the blank size and weight may change depending on the selected shape.

Applications in Tank and Vessel Work

This calculation is useful for storage tanks, air receivers, reactors, boilers, process vessels and fabricated industrial equipment. In addition, it helps with material purchase planning, costing, cutting layout and workshop estimation.
