Diameter in DN800 pipeline inner wall corrosion mostly adopts lining rubber or plastic processing and coating shedding is fatal to it. "Linear" auxiliary anode technology, the Department of our company has obtained a number of independent development of patented technology products. It solved the problem of the installation of the auxiliary anode of the small pipe wall. From then on the inner wall of the pipeline corrosion is no longer a problem.
The protection potential is uniform and the installation is simple, and the corrosion protection problem of the small caliber metal bare pipe is solved.
