Description
DIN2391 Seamless Steel Tube Drill Rod 1541 Steel Grade Oil Well Drilling Pipe With Casting Tube
1541 Grade Drilling Pipe: Comparative Advantages
1. Cost-Effective Champion
  • Lower alloy cost (no Cr/Mo like 4140) → 20-30% cheaper than high-end grades
  • Simplified heat treatment (normalized only) → Reduced processing expenses
  • Perfect for budget-sensitive, conventional wells
2. Reliable Strength for Standard Wells
  • Tensile: 800-950 MPa, Yield: 600-750 MPa → Matches 4130 baseline, sufficient for wells ≤3,000m & medium pressure
  • Elongation ≥16% → Balanced toughness, avoids brittle failure in routine operations
  • Outperforms low-carbon steel, no overkill for common depths
3. Easy to Weld & Maintain
  • Excellent weldability → No preheating/post-weld heat treatment needed for field connections
  • Good machinability → Faster threading/end finishing
  • Save time & labor costs on-site
4. Versatile for Common Formations
  • Ideal for soft-to-medium-hard strata (sandstone, shale, clay) with low abrasion risk
  • Fits vertical wells, shallow gas storage, or exploration holes
  • One tough solution for diverse routine drilling
Why 1541?
Cheaper than 4140/4130, but tougher than basic carbon steel. No premium features needed? 1541 delivers reliable performance at lower cost.
Applications
Fore poling (advance support), mine blasting, water well drilling, geothermal well drilling, and coal/nonferrous metal mining.
