High Load-carrying Capacity

The specially developed new composite material DRB-30 increases the maximum tensile strength of the drill pipe to 1020MPa, significantly enhancing both load-carrying capacity and service life.

Excellent Mechanical Properties

An innovative internal-external flow online heat treatment process is adopted to ensure outstanding comprehensive mechanical performance of the drill pipe.

Long Service Life

Equal-stress strength design reduces weight by 20% compared with traditional drill pipes.

Double-step, double-sided, and double-lead thread structure greatly reduces torque-to-tensile force conversion rate.

Patented large-pitch high-tooth thread design significantly extends thread service life and effectively ensures the safety of the drill rig under high-load operating conditions.
