2mm To 10mm Wall Thickness Palletized Quenched Seamless Drill Pipe
Palletized Quenched Seamless Drill Pipe (2mm–10mm Wall Thickness) is a robust drill pipe engineered for demanding drilling operations. Featuring a quenched seamless structure, it delivers high tensile strength (≥850 MPa) and hardness (HRC 28–32) for durability in abrasive formations. Available in wall thicknesses of 2mm to 10mm, it balances lightweight design with structural integrity, ideal for deep-hole or directional drilling. Precision-manufactured with tight tolerances (OD ±0.2mm, straightness ≤0.4mm/m) and optional corrosion-resistant coating (phosphate/nitriding). Palletized packaging ensures easy transportation, stacking, and on-site handling, reducing logistics costs. Suitable for geological exploration, oil/gas extraction, and mining applications.
