To combat galvanic corrosion, condensers...

🔍 Key Concepts

• Galvanic corrosion occurs when dissimilar metals are electrically connected in a conductive (often seawater) environment • Role of sacrificial anodes (like zinc, aluminum, magnesium) versus structural metals (like iron or steel) • How bonding/grounding systems and protective coatings are used together with or instead of sacrificial anodes on seawater side equipment

💭 Think About

• Think about which option directly addresses galvanic corrosion between copper‑nickel and other metals in seawater service • Ask yourself: are iron or steel normally used as sacrificial anodes, or are other metals usually selected for that purpose? • Consider whether bonding straps and coatings alone are sufficient, or if there is a typical standard practice for seawater‑cooled condensers with copper‑nickel waterboxes

✅ Before You Answer

• Verify which materials are commonly used as sacrificial anodes in marine seawater systems (zinc, aluminum, magnesium vs. iron/steel) • Check whether bonding straps are a corrosion prevention method by themselves or mainly a way to equalize potential between metals • Consider if protective coatings are normally used instead of anodes, or in combination with them in copper‑nickel condenser waterboxes
