How Hard Is Drill Rod?

The hardness of drilling rods for sale at TAIYE is amazing. Starting from the source, we have long-term cooperation with high-quality enterprises in the material industry such as Tianjin Pipe Group and Xining Special Steel Company to ensure the purity and stability of the raw materials; we have also developed the current domestic advanced channel-type automatic drill pipe quenching and tempering furnace, which is specially developed for the characteristics of small size, different lengths, high toughness of the rod body, and small radius of curvature of the trenchless drill pipe; in addition, TAIYE also holds a variety of general machining equipment with strong production capacity, which can guarantee the quality of drill pipe threads and drilling tools of various specifications.

How To Harden Drill Rod?

The drill pipe needs to ensure no cracks under the high load of irregular impact force. From the design stage, TAIYE has already considered the factors ensuring the long life of the drilling rods for sale during drilling operations under high torque and high pressure. Steel is the basis for ensuring the quality of drill pipes. The company attaches great importance to the control of purchased materials.  As the most critical process in the production of pre-hardened drill rods, the welding process can directly affect the failure rate and service life of drill rods. The company introduced the world's top drill pipe and rod production line, replaced the traditional manual welding with fully automatic robot welding, and solidified the soft process with hardware equipment, which not only improved the welding quality, improved the quality consistency, but also doubled the welding efficiency.
