About us
We specialize in producing and selling API standard drill pipe from 2-3/8''OD to 5-1/2''''OD.with steel grade E75,X95,G105,S135.We can supply both NC,IF,FH connection type and special connection type as HT55.Mainly used in oil and gas exploration and development process of deep well,horizontal well and extended reach well.
Drill pipe is a portion of the overall drill string. The drill string consists of both drill pipe and the drill stem which is the tubular portion closest to the bit or downhole assembly. Drill pipe and drill stems can be differentiated in that the drill pipe is quite flexible and produced in longer segments whereas the drill stem is much more rigid and manufactured in shorter task specific segments.
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. Hightorque 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
