Which maintenance practice helps minimize wear on the drill pipe?

• A. Replacing drill pipe daily with new sections.
• B. Lubricating moving parts.
• C. Drilling with maximum RPM at all times.
• D. Using drag bits in hard rock.

Answer: (B)

Lubrication of moving parts reduces friction and heat generated by the drill string’s rotation and movement. When surfaces slide against each other—such as at tool joints and connections—friction wears metal over time. A proper lubricant forms a protective film, cutting down metal-to-metal contact, lowering torque, and helping prevent galling and corrosion. Regular lubrication as part of maintenance keeps these surfaces sliding smoothly, which directly minimizes wear on the drill pipe. Replacing pipe daily is impractical and wasteful; drilling with maximum RPM increases wear and heat rather than preventing it; and using drag bits relates to bit performance, not maintaining drill pipe wear.
