Friction Welding Drill Pipe
Friction Welding Drill Pipe
Description
Friction welding drill pipes have specifications of φ89×10, φ114×8.56 and φ127×9.19. The thread standard is API standard and their threads are digital joint threads NC31, NC38 and NC50, respectively.
Friction welding drill pipe realizes the best combination of drill pipes and its pipe body and joint can adopt different materials. Though different heat treatments, the joints show high mechanical and wear resistant properties. Compared with integrated directional drilling pipes, friction welding drill pipes have longer service life and they also have light weight and good flexibility.
| O.D. (mm) | Wall Thickness (mm) | Pipe Body O.D. (mm) | Min. Bend Radius (m) | Max.Torque (KNM) | Pull Back (T) |
| 88.9 | 10 | 92 | 72 | 20 | 150 |
| 73 | 8 | 79 | 62 | 15 | 110 |
| 60 | 7.5 | 67 | 40 | 6 | 70 |

Advantages:
1. Use thread dope when screwing and unscrewing drilling pipes. Pay attention and don't damage the threads of drilling pipes when loading, unloading and moving. Lay flat and don't heavily press when stacking.
2. After construction, check drilling pipes one by one and clean threads and water holes. Coat thread dope and screw thread protector.
3. Mark scores and spiral nicks of drilling pipes if noticing and use carefully. If the score depth is more than 1mm or there are many spiral nicks, replace immediately.
4. Check the wear and tear of pipe body and treads after using for some time. Stop using in time if threads are broken or pipe body bends obviously.
