| Abstract: | Corrosion was a big problem in heat energy equipment and the cause of corrosion was complexity.The cause of cracking in reforming tubes was studied by dissecting the cracks, analyzing the crack's microstructure, testing rigidity of weld metal, analyzing micro-fracture in SEM. The results of those analysis showed that oxygen corrosion was the main reason of the reforming tubes cracking and the quality of welding was another important effect in this cracking. On the basis of this studying, some protective measures were proposed. |
