Q

Electrolytic corrosion in the condenser circulating water system can be reduced by __________.

🔍 Key Concepts

• Electrolytic (galvanic) corrosion and how dissimilar metals in seawater behave • Purpose and action of sacrificial anodes in seawater systems • Where corrosion actually occurs in a condenser circulating water system (tubes, waterboxes, seawater side vs. condensate side)

💭 Think About

• Which option directly addresses the metal surfaces in contact with the circulating seawater where electrolytic corrosion occurs? • Which choice sounds like a standard, well-known shipboard practice for protecting seawater-side components from corrosion? • Do any of the options deal mostly with condensate/steam side conditions instead of the seawater side, where this type of corrosion is usually a problem?

✅ Before You Answer

• Identify which choice involves installing sacrificial material that will corrode preferentially to protect more important metal parts. • Eliminate any options that only change quantity or flow of water without changing the electrical/corrosive conditions at the metal surface. • Make sure the selected option clearly applies to the seawater side (waterboxes/tubes), not just to the condensate/hot well side.
