🔍 Key Concepts

• Difference between soft scale and hard, adherent scale in heat exchanger tubes • Effects of abrasive mechanical tools vs. gentle methods on thin-walled tubes • Typical shipboard maintenance practices for seawater-cooled shell-and-tube heat exchangers

💭 Think About

• Ask yourself: For soft deposits that are not firmly bonded, what is the simplest, least aggressive way to restore flow and heat transfer? • Which method minimizes the risk of damaging or thinning the tube walls while still being practical for routine maintenance? • Which option sounds more appropriate for heavy, hard scale versus light, soft fouling?

✅ Before You Answer

• Identify which options use aggressive cutting/reaming or high-impact action that could harm tube material. • Look for the choice that combines mechanical but gentle action and/or flushing rather than strong chemicals or cutting edges. • Consider normal preventive/routine cleaning versus methods usually reserved for severe, hard scale fouling.
