The use of bellows expansion joints is an effective method to rationalize various piping systems in industry. In the structural design, the requirements for preventing failures such as ratchetting, fatigue, and buckling should be satisfied. The mechanisms of some failure modes of bellows are different from those of vessels and piping components. It is a particularly unique characteristic that bellows buckle under internal pressure. In the case of hightemperature operation, the possibility of creep buckling should be considered. The author has proposed an evaluation method for column-type creep buckling of bellows under internal pressure. In this study, the creep deformation behaviors of bellows are investigated using finite element nonlinear analyses and the validity of the evaluation method is discussed.
