Made in China Water Well and Borehole Drill Pipe and Drilling Rod

Made in China Water Well and Borehole Drill Pipe and Drilling Rod


Features:

GD Drill rod is made of high quality material detected by spectrograph, impact and tension test.
With fully digitized processing line introduced from Japan with integral heat treatment equipment
Anti adhesion thread with nitrogen treatment on surface make it easier for handling.
Metallography detection, hardness test, magnaflux inspection, ultrasonic flaw detection, tensile test and impact test ensure products quality.


Drill Pipe Features:

A. High precision in size and shape
B. Good low temperature toughness
C. Excellent comprehensive mechanical properties
D. High connection strength and sealability
E. Large inside diameter of tool joint
F. High torque resistance
G. High fatigue strength and long fatigue life


Internal Coating Feature:

A. High abrasion resistance and low friction factor
B. Good adhesion and flexility
C. High application temperature and pressure
D. High hardness and impact resistance
E. Good corrosion resistance


Hardbanding Feature:

A. Good balance between antiwear and friction-reduction
B. The wear rate is less than 6% of that of bare tool joint, which can prolong 3 times of the
Tool joint service life
C. Good property of friction-reduction, which can reduce the casing wear to the least, and its
Wear to casing is less than 11% of that of bare tool joint
D. Reduce the torque of drilling string
E. Good weldablity with little splash and good rewelding preformance
F. Friendly to environment
