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
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.
