🔍 Key Concepts

• Erosion and abrasion in heat exchanger tubes usually occur right where the cooling water first strikes the tube end • Think about what can be placed at the inlet end to take the wear instead of the tube metal itself • Differentiate between devices for corrosion protection (like zincs) and devices for mechanical wear protection

💭 Think About

• Which option is specifically placed where high-velocity water impacts the tube ends and can be easily replaced when worn? • Which choices relate more to corrosion or sealing, rather than to taking the brunt of physical erosion and abrasion? • On a marine exam, how are zincs normally used on the waterside of systems—what type of damage are they meant to prevent?

✅ Before You Answer

• Identify which answer protects against mechanical wear (erosion/abrasion), not chemical attack (corrosion). • Check which items are typically sacrificial or replaceable pieces installed at the tube inlets. • Eliminate any options that mainly serve corrosion protection instead of impact/erosion protection.
