摘要
详细的分析了炼油厂制氢装置常见的几种腐蚀类型,包括高温氢腐蚀、CO2腐蚀及碳酸盐应力腐蚀开裂。并提出制氢装置的高温氢腐蚀环境选材通常为20#钢和15CrMo;CO2腐蚀环境选材通常为奥氏体不锈钢;碳酸盐应力腐蚀开裂环境选材通常为304L,另外严重时还应要求焊后热处理。
Several comman kinds of corrosion including hydrogen corrosion, CO2 corrosion, and carbonate stress corrosion cracking of hydrogen unit in the refinery industry corrosion environment piping shall be 20# or 15CrMo. In CO2 austenitic stainless steel. In carbonate stress oddition, severe cases should also require post are studied in this paper. In hydrogen corrosion environment piping shall be corrosion cracking environment piping shall be 304L. In -weld heat treatrment.
