Extension Rod
Make Hexagonal and round cross sections, Hexagon rods are far more rigid, heavier and transfer strength more successfully, even though growing flushing. Spherical rods are normally lighter than hexagonal rods and are typically utilised in extension drilling programs. With the more time steel tending to be bigger in diameter, conventional extension steel is characterized by a duplicate thread on each and every stop of the metal.,
Male/Female (M/F) rod, velocity rod
M/F drill metal is an substitute to couplings sleeves to contain the feminine portion of the threaded link as an integral component of the drill steel. M/F drill steel supplies far more rigid connections and is less complicated to uncouple and take care of. The service life also tends to be much better than with individual couplings. The positive aspects of drilling with M/F steel consist of: Easy dealing with, more quickly uncoupling, tighter connections, the prospective to drill straighter holes, and more time service life.
For Extension Rod and M/F metal process, the under two diverse kinds of warmth treatment method are employed to improve substantial velocity and powerful percussive drill string factors to optimize their functionality and reliability. More time metal more substantial in diameter, traditional extension metal, Hexagonal and round cross sections are available.
– Carburization is a process utilized to harden the complete rod surface the two internally and externally to bolster and prolong the life of the rod.
– Higher Frequency Induction is a procedure exactly where only the thread ends of the rod are hardened to lengthen thread lifestyle.
