Pressure Vessel Design and Calculators

To calculate the Longitudinal Stress in a thin wall pressure vessel use the following calculator. Note that the Hoop stress is twice that of the longitudinal stress for a thin wall pressure vessel. Therefore, the Hoop stress should be the driving design stress.
