Spiral steel pipe itself has no life limit, and the service life is mainly related to the operating environment and production process. Spiral steel pipe operating environment is relatively poor In order to extend the service life, the oute.
Drill Pipe,Oil Drill Pipe
API Oil Drill Pipe
Standard: API 5D
Size: 60.3 ~ 168.3mm
Grade: E75,X95,G105,S135
Application: Drill Pipe
API Oil Drill Pipe
Main feature:
A. The drill rods comply with the provisions of API SPEC 5D & API SPEC7.
B. The grade of steel are determined according to the requirements of Group 1 & Group 3 of API SPEC 5D.
C. Drill pipe joints at the same level comply with the provisions under the Standard API SPEC 7.
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
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
