API SPEC. 5DP Drill Pipe steel grade G105, S135, Petroleum Drill Pipe in Oil and Gas Equipment

1) Internal Plastic Coating: TC2000, DPC2000, TK34, TK34P

2) Steel Grade: E75, X95, G105, S135

3) Length: R1  18-22 feet;  R2  30.5-31.5 feet;  R3  38-45 feet 

4) All drill pipe are made according to API 5DP

5) We can provide in many conditions, with or without hard banding (Arnco 100XT, Arnco 300XT, BoTn 1000, BoTn 3000).

Drill Pipe Feature:

1). High precision in size and shape

2). Good low temperature toughness

3). Excellent comprehensive mechanical properties

4). High connection strength and sealability

5). Large inside diameter of tool joint

6). High torque resistance

7). High fatigue strength and long fatigue life

Internal Coating Feature:

1). High abrasion resistance and low friction factor

2). Good adhesion and flexility

3). High application temperature and pressure

4). High hardness and impact resistance

5). Good corrosion resistance

Hardbanding Feature:

1). Good balance between antiwear and friction-reduction

2). The wear rate is less than 6% of that of bare tool joint, which can prolong 3 times of the tool joint service life

3). 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

4). Reduce the torque of drilling string

5). Good weldablity with little splash and good rewelding preformance

6). Friendly to environment
