| Abstract: | An inspection has been made on the radiation tubes, convection finned tubes, cracked fins, spalled parts and collected oxidized materials in the methanol converter in Sichuan Vinylon Plant in respect of structure, fracture form and welding by electronic scanner, X-ray examinations etc. The comparison and construction were qualitatively analyzed. The results showed that the tube cracks, finned tube failure and spalling were caused by the temperature run-away of the converter. |

| Keywords: | furnace tube radiation section convection section finned tube high temperature cracking |
