🔍 Key Concepts

• Powered rotary brush operation in boiler tubes and how motion affects friction and binding • Consequences of holding a rotating tool still inside a tight metal tube • Difference between protecting the tube, the brush, and the tool drive

💭 Think About

• Think about what happens mechanically if a powered rotary brush is held still and pressed against the tube wall inside a close-fitting tube. • Which problem would occur first: long-term issues like pitting, slow wear of bristles, or an immediate mechanical problem affecting the brush and drive? • Which option describes a condition that could suddenly stop the tool and potentially damage the equipment or injure the operator?

✅ Before You Answer

• Identify which choice describes an immediate mechanical hazard, not a gradual wear or corrosion issue. • Ask yourself whether brief cleaning motion can realistically reduce pitting inside a boiler tube or if pitting is controlled by water chemistry and maintenance instead. • Decide which answer focuses on the powered brush’s tendency to bind or lock in the tube if not moved continuously.
