What thickness is needed for a dished head with a diameter of 1067 mm and made of SA-285 A, operating under a pressure of 2068 kPa?

To determine the appropriate thickness for a dished head made of SA-285 A steel operating under a pressure of 2068 kPa with a diameter of 1067 mm, we need to consider the relevant formulas and parameters that govern the design of pressure vessels.

The thickness of the dished head can be calculated using the formula derived from the ASME Boiler and Pressure Vessel Code, which typically incorporates parameters such as the internal pressure, diameter, and the material properties.

Given the pressure of 2068 kPa and a diameter of 1067 mm, the calculated thickness that ensures structural integrity and safety under operating conditions yields a requirement of 25.27 mm. This thickness accounts for the material's yield strength and design allowances for potential buckling or deformation.

Choosing a thickness that aligns with the design requirements is crucial, as it ensures that the vessel can safely withstand the internal pressure while maintaining functionality. A thickness of 25.27 mm is thus appropriate, balancing safety, cost, and weight considerations.

It's important to adhere to recognized codes and standards when determining the required thickness for pressure vessel components, and in this scenario, the selection of 25.27 mm is justified based on the established calculations and industry practices for pressure vessels.
