製品説明

NQ Wireline Drill Rod - 3 Meter Length

The NQ Wireline Drill Rod is a premium core drilling solution designed for mineral exploration and geotechnical investigation. Manufactured from high-grade seamless alloy steel tubing and case hardened for superior wear resistance, this 3-meter rod delivers exceptional performance in demanding drilling environments.

Key Features

  • Case Hardened Surface: Heat treated to HRC 38-42 for extended service life and reduced wear in abrasive formations
  • Seamless Alloy Steel Construction: 4130 chromium-molybdenum steel ensures high tensile strength and fatigue resistance
  • Precision Thread Connection: API standard tapered thread with phosphated surface treatment prevents galling and ensures leak-tight joints
  • Full Length Heat Treatment: Uniform hardness distribution throughout the rod body for consistent performance
  • Straightness Tolerance: ≤1.0mm per meter ensures smooth rotation and reduces vibration during drilling
