System to utilize the power flow bracelet anode for corrosion protection of underground well casing section which is shielded by the cement in the cellar space , devices , and methods

摘要

Cathodic protection system , due to the underground well casing having an upper section which is surrounded by the applied current cathodic protection circuit that passes through the soil media in the well casing which is substantially shielded by the seller , are provided . Applied current cathodic protection circuit , in order to corrosion the lower section which is not enclosed in the well casing , is provided . In order to corrosion the upper section encompassed the well casing , the additional cathodic protection circuit is provided . Said additional cathodic protection circuit is a galvanic anode cathodic protection circuit comprising one or more of the bracelet flow conductive anode are placed in the upper section in the circumferential direction which is the upper section and the surrounding is enclosed in well casing . Upper section and said one or more of the bracelet flow power anode is surrounded of well casing is substantially surrounded it by rice cellar back , galvanic anode cathodic protection circuit , over a wide range of non- homogeneity within the range of rice cellar back , it is equally effective .
