THK Design Calculation

This document provides calculations for the minimum required thicknesses of an air receiver tank according to ASME standards. It includes the design data, material properties, and calculations for both the shell and dish sections. For the shell, with an inside diameter of 1500mm and allowable stress of 1167.1kg/cm^2, the minimum required thickness is 10.11mm and a thickness of 12mm is provided. For the dish, with inside crown radius of 1350mm and knuckle radius of 255mm, the minimum required thickness including corrosion allowance and thinning is calculated to be 12.44mm, and a thickness of 14mm is provided.
