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.​
