Non-Rotating Drill Pipe Protector: Eliminate Casing Wear in Directional Drilling
The Casing Wear Crisis in Modern Drilling
Rotating drill strings cause:
-Costly casing damage requiring $500K-$1M replacement per well
-40% higher torque in extended reach laterals
-Well integrity risks from worn casing strings
Our non-rotating protector delivers:
✅ 80% reduction in casing wear
✅ 25% lower rotational torque
✅ Zero rotation against casing wall
How It Works: Stationary Protection Technology
Three-Component Design
| Component | Function | Innovation |
| Central Mandrel | Rotates with drill string | Hard chrome plating for wear resistance |
| Composite Sleeve | Stationary against casing | Glass-reinforced polymer with lubricity |
| Retaining Collar | Prevents axial movement | Quick-install clamp design |
→ Composite bearings allow rotation while outer sleeve remains stationary
→ Self-lubricating materials require no maintenance
Operational Advantages
✅ Casing Protection
Eliminate casing wear in build sections and laterals
Extend casing life for multiple well re-entries
✅ Drilling Efficiency
Reduce surface torque by 20-25%
Enable longer laterals with less drag
✅ Economic Value
Save $250K+/well on casing replacement
Reduce tripping time by eliminating wear checks
