It is a responsibility for every structural engineer of power plants, refineries, gas plants and chemical plants to design and construct high quality pressure vessels and piping system. To complete this responsibility, it is very important to understand failure modes of pressure vessels, piping and their components, relation between each failure mode and stresses, and design consideration to prevent the failure. In this paper, basic characteristics of each failure mode are described with several examples of failure accident. Typical failure modes described here are a ductile rupture, brittle fracture, excessive deformation, instability (buckling) , progressive deformation (ratcheting) , fatigue fracture, creep rupture, creep ratcheting, creep-fatigue interaction, creep buckling, and environment effect on cracking. For these failure modes, the relation with stresses and design consideration are emphasized.
