🔍 Key Concepts

• Heat exchanger tube fouling types: soft biological growth vs. hard mineral scale • Differences between mechanical cleaning tools (brushes vs. reamers) and when each is used • Risks and benefits of chemical descaling inside thin-walled tubes

💭 Think About

• Which method is best suited for hard, stubborn mineral scale rather than soft slime or light fouling? • What are the potential risks of using aggressive mechanical tools inside thin tubes compared with other methods? • In routine shipboard practice, what method is commonly used when mechanical brushing is no longer effective on heavy scale?

✅ Before You Answer

• Identify whether the question is emphasizing hard scale or light deposits • Consider potential damage to tube walls from each option • Ask which method is usually considered most effective and practical for heavily scaled, seawater-cooled tubes on board ships
