| Abstract: | The corrosion problems in furnace pipe of original cracking furnace due to cumulative carbonization and carbon penetration under high temperature are analyzed. Then, the radiation furnace pipe made of high Cr-Ni alloy 35Cr45NiNb is used to replace the original furnace pipe. The production data of both pipes are completely compared. Moreover, the experience and method about the replacement and welding of furnace pipe are also summed up. |
