Drill Pipe
Owetech drill pipe and heavy weight drill pipe are manufactured using high-quality seamless steel pipe that was machined using advanced CNC equipment and state-of-the-art friction welding technology. These drill string components boast high strength, high bending resistance and a reliable, firm weld that can be trusted for extended use. Owetech drill pipes are used to effectively ensure an accurate vertical drilling operation. Drill pipes are one of the most essential drilling tools found at oil fields. We have various models for you to choose from depending on your specific oil drilling needs. All of our drill pipes are produced in compliance with API requirements.
The mechanical indexes of our drill pipe products not only meet, but exceed all API standards.
