Stress in Pressure Vessel Shell Wall

A pressure vessel has to retain to pressure.  In doing this the pressure applies two types of stresses in a pressure vessel.  They are circumferential and longitudinal.

Pressure Vessel Stress in Shell Wall

What is important to remember is longitudinal stresses are half as much as the circumferential stresses. Therefore, we can say that longitudinal strength is twice as strong as circumferential strength.

 What is important to remember is longitudinal stresses are half as much as the circumferential stresses. Therefore, we can say that longitudinal strength is twice as strong as circumferential strength. This is only true for illustration purposes.
