Drill pipe Feature:
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
