API drill pipe drilling pipe

         We are equipped with facilities of top quality in the world, such as hydraulic upset forging machine, walking beam quenching furnace,, hot and cold straighten device, friction welding machine, middle frequency heat treatment, numerical control lathe and compete set of ultrasonic inspection and magnetic particle inspection. The whole process includes hot upset forging, heat treatment, hot straightening, could straightening, ultrasonic inspection on pipe body and pipe end, magnetic particle inspection, friction welding, seam inspection. We strictly carry out API spec Q1 quality control system and API Spec 5DP production standard. We have a complete set of inspection process, inspection for raw material, magnetic particle inspection to pipe end, ultrasonic inspection on pipe body, inspection on weld seam linearity testing and visual inspection

 

API drilling pipe:

1)drill pipe OD: 2 3/8", 2 7/8", 3 1/2", 4", 4 1/2", 5", 5 1/2"

2)API drilling pipe Steel Grade: E75,X95,G105,S135
3)Type of end finish : EU-external upset,

                                  IEU-internal & external upset

4)All seamless steel drill pipes are made according to API 5 Drill pipe standards.

5)We can provide seamlesssteel pipe according to customers' requirements.

 6) Wall thickness: 7 - 12.7 mm or 2 3/8"-5 1/2"

7)length: 5.49-12.5m

 

Regarding the Drill Pipe,the OD from 2 3/8” to 5 1/2” and steel grade from E75 to S135. Mainly used in oil and gas exploration and development process of deep well, horizaontal well and extended reach well. With the Hardbading and Internal Coating.

Hardbanding:

1. Avoid drill pipe wear and prolong life
2. Avoid friction caused by thernal cracking failure of drilling joints.
3. The wear-resisting coefficient has reduced performance with wear casing.

Harbanding Type:

1. Arnco-100XT
2. Arnco-200XT
3. Arnco-300XT
4. AMRMACO M
5. TCS 8000
6. BoTn 3000
7. BoTn 1000
