This paper introduces the industrial-scale test of the domestic anodicallv protectedstainless steel shell-and-tube cooler in 93% sulphuric acid. Operating experience shows that the anodic protection system works successfully. The sealing structure of rod reference electrode is highly reliable. The maximum corrosion rate of the anodically protected stainless steel specimen in 93% sulphuric acid for six months is 0.036mm/a.
