Devices of cathodic protection horizontal tanks against internal corrosion

摘要

The invention relates to the field of oil industry, and can be used for cathodic protection bottoms horizontal tanks from corrosion. The technical result is to increase the efficiency of electrochemical protection of horizontal tanks against internal corrosion. Cathodic protection device includes a constant current source connected to the negative pole of the horizontal tanks, which is the cathode, and the positive - to the electrode is an anode. Wherein the electrode is U-shaped and the sump above the bottom horizontal attachment on the support and has an operating envelope of electrically conductive oil-resistant elastomer, which is placed inside conductive metal. 15 ZP f-ly, 3 Fig.
