摘要：

This paper gives a case study about the failure of steam pipe fitting equipment in a chemical factory. The observation and analysis are done by way of SEM, EDS, tensile tests, and fracture mechanics. The reasons for failure, the fracture mechanisms, and the failure modes are revealed and discussed. A prediction of the fatigue life of a bolt of the fitting flange is made. (c) 2005 Elsevier Ltd.
