Special Topic on Equipment Corrosion Monitoring Technology (1) – The Development of Corrosion Monitoring Technology in China

Thread Content

The development of corrosion monitoring technologies abroad began with resistance monitoring methods, and later methods such as electrochemistry and inductance were developed. Corrosion monitoring in China originated from electrochemistry, namely the development and application of weak polarization techniques; later, resistance and inductance monitoring techniques emerged, with Researcher Zheng Liqun from the former Metal Research Institute being a key figure in this field. Currently, the methods used for corrosion monitoring in the refining industry are mainly inductive and pH monitoring. In the refineries owned by CNPC, Sinopec, and CNOOC, the coverage of equipment corrosion monitoring is already quite high. Given the characteristics of equipment corrosion, it is essential to monitor corrosion in units involved in atmospheric and vacuum distillation; meanwhile, corrosion monitoring systems have also been widely adopted in catalytic and reforming units, as well as across entire refineries.
