Description
GB/T 9808 Standard Oil Drilling Pipe 1541 Steel Drill Rod Tube with High Straightness
1541 Grade Drilling Pipe - Simple, Strong & Affordable

Need a reliable, budget-friendly drilling pipe for standard wells? 1541 grade is your go-to solution.

Why It Works
  • Solid Strength - Handles wells up to 3,000m with 800-950 MPa tensile strength - enough for most jobs
  • Tough Enough - 16% elongation absorbs minor shocks (like tripping or rotation) without breaking
  • Easy to Weld - No special prep needed - just weld and go
  • Wears Well - Better than basic carbon steel, great for soft to medium rock (sandstone, shale)
  • Low Cost - No fancy alloys - just affordable performance for everyday drilling
Perfect For
  • Shallow to mid-depth wells (≤3,000m)
  • Stable formations (low abrasion)
  • Projects watching costs
Applications

Applications include mine blasting, water well drilling, geothermal well drilling, fore poling (advance support), and coal and nonferrous metal mining.
