Liande 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. Liande 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.
Features
1. The geotechnical drill pipe's body and joint are constructed from alloy steel tubing and structural alloy steel and treated with vacuum tempering. As a result, its strength and resistance to wear is effectively increased.
2. We use a friction welding technique that won't melt material so our alloy drill pipe has a smooth surface and a high bending strength.
3. Made by high precision CNC machines, this drilling product is durable and strong.
Our drill pipe comes in different diameters (50, 60, 73, 76, 89, and 114mm) and specifications (AQ, BQ, NQ, HQ, PQ, AW, BW, NW, HW, PW, AWG, BWG, NWG, HWG, PWG, AWY, BWY, NWY, HWY, PWY, etc.). Customized pipes are available upon request.
