本文讨论了储水罐的阴极保护方法，这些方法可以防止腐蚀，并且长期经济。讨论了以下主题:腐蚀机理；腐蚀控制的必要性；阴极保护设计；电解质电阻率；阳极材料；整流器；和维护。建议使用自动控制的固态整流器，该整流器测量维持电位时无IR压降误差。在遇到结冰情况时，建议使用镀铂铌丝的浮力、长寿命阳极系统，但也可以使用可更换的铝阳极。 当不存在结冰条件时，高硅铸铁阳极可用于储罐。然而，所有系统必须进行适当维护，以确保持续有效运行和最佳腐蚀控制。包括11个参考文献、表格、图表。

This article discusses cathodic protection methods for water storage tanks, which protect against corrosion and are economical over the long term. The following topics are addressed: the corrosion mechanism; the need for corrosion control; design of cathodic protection; electrolyte resistivity; anode materials; rectifiers; and maintenance. Automatically controlled, solid-state rectifiers, which measure the maintained potential without IR drop error, are recommended. Where icing conditions are encountered, a buoyant, long-lived anode system using platinized niobium wire is recommended, although replaceable aluminum anodes can also be used. High-silicon cast-iron anodes can be used for tanks when icing conditions do not exist. All systems must be properly maintained, however, to ensure continued effective operation and optimum corrosion control. Includes 11 references, table, figures.
