Abstract：The general test methods for the fatigue life of the bellows expansion joint are introduced.The requisitions to the fatigue life of the bellows expansion joint are different,because the functions of the bellows expansion are different.The best reliable method to examine the rationality of the design and manufacture for bellows expansion joint is to determine the real fatigue life of b ellows expansion joint,So they are very important.
Key Words：Bellows，Expansion joint，Fatigue life.
