火炬管线腐蚀分析与防护措施

碳钢火炬管线使用10年后，发现管线底部出现腐蚀，管内壁上面覆着大面积腐蚀产物，腐蚀减薄严重，甚至局部腐蚀穿孔，蚀孔由管内向管外方向扩展。对腐蚀气分火炬管线及管内壁腐蚀产物进行技术检测，解析腐蚀原因，进而提出防护措施。

The Corrosion Analysis and Safeguard for Torch Pipe

After torch pipeline of the Carbon steel is used for 10 years, the corrosion is found at the bottom of pipeline. A lot of corrosion is found on the inner wall of the pipe. The corrosion makes the wall of the pipe thinner, even the pore appears on some part of the wall of pipe. The pores expend from the inside of the pipe to the outside of the pipe. The corrosive pipe of gas separation torch pipe and the corrosive products of the inner wall of pipe is study. The reasons of corrosion . were analyzed, in addition raise the safeguard.
