Drill Pipe
Manufactured from high-grade low-carbon steel, our pipes deliver superior tensile strength and fatigue resistance; precision friction-welded joints create a single, solid unit that withstands cyclic compression and extrusion for long, reliable service in mining, water-well, geothermal, oil and all DTH rock-drilling operations
Drill Pipe – Product Highlights
Material
-
High-quality low-carbon or alloy steel for balanced strength and toughness
-
Full traceability from certified billet to finished pipe
Manufacturing Process
-
Friction-welded joints: pipe body and tool-joint forged as one piece, 100 % ultrasonic inspected
-
Internal-external upset (IEU) design increases tensile strength and fatigue life
-
Precision CNC threading ensures perfect hand-tight make-up and repeatable torque
Performance & Reliability
-
Wall thickness 4 – 12 mm, length 1 – 9 m on request; strict ovality ≤ 0.5 %
-
Working torque up to 12 000 N·m; safety factor ≥ 2.5
-
Surface shot-blasted + black or copperized finish for maximum thread anti-galling
Quality Assurance
-
Each pipe hydro-tested to 1.5 × working pressure
-
Full set of mill certs, UT & MT reports provided with shipment
Sustainability & Cost
-
Light-wall options reduce rig weight and fuel consumption
-
Modular Box-Pin or quick-connect ends allow rapid on-site make-up and re-use
