- Customizable thread types and drill pipe lengths available upon request
- Material selection conforms to API standards for reliable performance
- Twice-thickening molding technology creates stable, smooth transition zones
- National initiative integral drill rod with intermediate-frequency heat treatment
- Liquid nitrogen treatment process extends thread life significantly
Rod bodies utilize premium domestic steel materials with thickening processes at both ends. After friction welding, rods undergo tempering processes, heat treatment, and surface nitriding to eliminate common failure modes like thread gluing, burst fractures, and diameter issues.
Precision CNC lathes and custom molding tools ensure thread quality conforms to international standards, resulting in stable, reliable drill pipes with extended service life.
