Extension Rod
Produce Hexagonal and spherical cross sections, Hexagon rods are more rigid, heavier and transfer strength more successfully, although increasing flushing. Spherical rods are generally lighter than hexagonal rods and are usually utilized in extension drilling programs. With the for a longer time steel tending to be greater in diameter, typical extension steel is characterised by a copy thread on every stop of the metal.,
Male/Feminine (M/F) rod, speed rod
M/F drill steel is an substitute to couplings sleeves to incorporate the female portion of the threaded link as an integral part of the drill metal. M/F drill metal supplies much more rigid connections and is easier to uncouple and manage. The support existence also tends to be better than with independent couplings. The rewards of drilling with M/F metal contain: Effortless dealing with, a lot quicker uncoupling, tighter connections, the likely to drill straighter holes, and lengthier services life.
For Extension Rod and M/F steel approach, the beneath two various types of warmth treatment method are utilised to improve substantial velocity and powerful percussive drill string elements to optimize their functionality and reliability. More time metal bigger in diameter, typical extension steel, Hexagonal and round cross sections are available.
– Carburization is a approach utilized to harden the entire rod area each internally and externally to improve and extend the existence of the rod.
– Substantial Frequency Induction is a procedure exactly where only the thread ends of the rod are hardened to lengthen thread life.
