    Shell Thickness Calculator

    Uploaded by

    Azaharimahadi
    This document provides information for calculating the thickness of the wall (shell) of a cylindrical tank. It lists the design pressure, density of contents, gravity, tank height, and other parameters. It then shows the calculations to determine the required thickness based on these parameters, which is 0.23104063 mm. Adding a corrosion allowance of 0.079 inches, the overall recommended thickness is 2.23764063 mm.
