What are the failure modes of pressure vessels?

When a pressure vessel loses its normal working ability due to excessive mechanical load or temperature load, it is called failure. There are three forms: 1. Strength failure: The container undergoes excessive plastic deformation or rupture under load. 2. Stiffness failure: The container undergoes excessive elastic deformation, causing difficulty in transportation and installation or loss of normal working capabilities. 3. Stable failure: The container suddenly changes shape under load, resulting in loss of working ability. The design of pressure vessels must take into account the above three possible failures and give them comprehensive consideration to ensure the normal use of the equipment.
