Product name: T38 Thread 1525mm Length Diamond MM Extension Rod For Rock Formation Drilling
Product category: Drilling rod
Threaded Connection: T38
Length: 1525mm
KINGDRILLING high-strength alloy steel is used to manufacture threaded drill pipe. High precision CNC machine for machining all tracks and threads. Rapid heating and cooling is used to produce threads after induction hardening. Precision temperature control heat treatment equipment improves the mechanical properties of drill pipe and ensures the service life of drill pipe.
Full carburizing hardens the outer steel body and increases the carbon content of the drill pipe outer layer. Drilling on complex rocks and terrain can be accomplished with high precision and efficiency by using a solid threaded bit that fits precisely into the inner wall of the bit.

FAQ:
1. How should one use a drilling pipe?
The instrument used to transfer power during drilling operations is the drill rod. Typically, the drill string is made up of a number of parts, including Kelly, stabilizers, drilling pipe, drill collars, and special connectors. Drill string functions include: (1) regulating drill bit; (2) applying weight on bit (WOB); (3) conveying power; (4) transporting drilling fluid; and (5) carrying out special activities such as handling subterranean accidents and cement extrusion.
2. What are the benefits of using heavy-duty drill pipe?
a. When drilling a deep well, heavy weight drill pipe can replace a portion of the drill collar, improving load, decreasing torque, and increasing drilling capacity.
b. To remove the safety clamp and sub that were not in use during the drilling operation; this is a simple process that can reduce trip time.
c. In directional wells, fast speed, low torque drilling minimizes string abrasion and fracture without differential pressure and sticking due to drill collar's lower steel grade and tiny touching area with the well wall.
3. What is a drill rod?
A drill rod is a form of bar stock machined to produce tools such as drill bits, taps, dowel pins, shafts, reamers, files, punches and hammers. It's soft enough to shape but can be heated up to revert back to the hardness. Drill rods are manufactured from tool steel that has been ground to a tight tolerance diameter.
