After two months of service, the heat pipe of hydrogen production unit bulged and fractured. The observation and measurement of the deformation of the pipeline was performed. The failure mode of heat pipe was analyzed by observing the macro and micro morphology of the fracture surface, and by Energy Dispersion Spectrum (EDS) analysis. Through the analysis of the metallographic structure of the pipeline, it is found that the pearlite is seriously spheroidized, which indicates that the pipeline has failed under long-term overheating working condition.
