Q

To minimize corrosion, what are fuel oil strainer disks, spacers and scraper blades made of?

🔍 Key Concepts

• Corrosion resistance of different metals commonly used in marine fuel systems • How fuel oil (with sulfur and other contaminants) interacts with metals over time • Why certain alloys are preferred for seawater and fuel service components

💭 Think About

• Look at each choice and ask: which metals are known to corrode faster in oily, possibly sulfur-containing, marine environments? • Think about which metals are often used on ships for strainers, valves, and fittings that must resist both seawater and fuel corrosion. • Consider whether soft, easily damaged metals would be suitable for scraper blades and strainer parts that see mechanical wear.

✅ Before You Answer

• Eliminate metals that are more prone to rapid corrosion in the presence of sulfur and moisture. • Consider which options are commonly used in marine fittings that require high corrosion resistance (e.g., in seawater and fuel oil). • Ask which material(s) are known as corrosion-resistant alloys specifically designed for harsh marine environments.
