OuChuang’s R&D team has been developing conductive polymer-based flexible anodes (without pre-filled materials) since the early 1990s. It is the earliest and successful team in China to develop flexible anodes. Its conductive polymer-based flexible anodes After testing, it has reached the level of similar foreign products, and has been successfully applied to many key projects since 1997. Classical application examples include: the 21-kilometer cathodic protection project of the Beijing Yamenkou-Liangxiang gas pipeline, which was put into use in 1999 on the first line of Shaanxi-Beijing, is currently operating well. It has become a project where flexible anodes in China have been successfully applied to long-distance pipelines with early and long service periods.
