ASTM A513 A519 Tight Tolerances Drill Rod 45MnMoB Low Eccentricity Seamless Steel Oil Drilling Pipe

​​45MnMoB Drilling Pipe – Built for Extreme Wells​​
      ​​Toughness meets strength for the harshest drilling conditions.​​ The 45MnMoB-grade pipe delivers ​​unmatched load capacity, superior wear resistance, and rugged durability​​ where standard pipes fail.

 

​​Why It’s Different​​
1. ​​Extreme Strength​​ – Handles ​​ultra-deep wells (>3,000m) & high-pressure reservoirs (≥50 MPa)​​ with tensile strength ≥790 MPa.

 

2. ​​Rock-Hard Wear Resistance​​ – Manganese & molybdenum boost hardness (QT-treated up to 28–32 HRC) to fight abrasion.

 

3. ​​Impact-Ready​​ – Absorbs shocks (stuck pipe, vibrations) with ≥14% elongation.

 

4. ​​Corrosion & Heat Resistant​​ – Low sulfur/phosphorus + molybdenum for tough fluids & high temps.

 

5. ​​Weldable & Tough​​ – Field-ready welding & machining for demanding jobs.

 

​​Perfect For:​​ Ultra-deep, high-wear, or HPHT wells.

 

​​Upgrade when 1541/4130 can’t keep up.​

 

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