2. Description
Quality Drill Pipe requires cutting edge equipment.
Our Drill Pipe product line is completely automated with equipment from Germany & the U.S., such as the Friction Weld machine, Hardbending Weld machine, IPSEN furnace and Siemans CNC Lathe.
The Tool Joints are made of AISI 4137H premium alloy steel fully Q&T with the IPSEN Furnace.
All the joints are inspected by Florescence Magnetic Particle and the Ultrasonic method. The pipe body goes under very serious inspection in conformance with API. 5D.
The welding between the drill pipe an tool joint is accomplished with the Friction Welding machine, the welding process is swift & steady under computer control. The weld zone is quenched and tempered through the Induction process which is computer controlled in real time.

3. Pup joint
We can supply pup joint, manufactured from the integral AISI 4145H alloy steel.

4. Carbide wear-resistant banding and internal coating
To increase the abrasion resistance and erosion resistance of drill pipe products in drilling operation, our company can provide wear-resistant banding and internal coating for drill pipes.
We can weld banding on the internal joint diameter of drill pipe and 18°shoulder of box according the API standard or your requirement. The types of banding include Tungsten Carbide, ARNCO 100XT、ARNCO 300XT and TCS.
