Sansung rock drilling extension rod are manufactured with high good quality of alloy steel bar and tungsten carbides with excellent dress in resistance and impact toughness superior, via heat treatment so that it can face up to the toughe EPT rock drilling requires, and transmit intense influence strength into the rock with the lea EPT feasible reduction of strength. They are commonly utilised in all types of mining, drilling, quarrying, engineering, development, drinking water effectively drilling, oil exploring industries and so forth.
Extension rod:
EPT names are Extension drill steel, Extension drill rod, and Extension metal, M/Frod (Pace rod), generate Hexagonal and spherical cross-sections,Hexagonal rods are more rigid, heavier and transfer energy a lot more efficiently,whilst increasing flushing. Round rods are usually lighter than hexagonal rodsand are generally used in extension drilling apps. With the more time steel tending to be bigger in diameter, traditional extension steel is characterizedby replicate thread on each and every stop of the metal.
Extension rods are made by hollow drill steels, different lengths are accessible from 600mm to 6400mm. This hollow hole are typically named flushing hole, used for transmitting drinking water or air throughout drilling. And the threads can be utilized for connecting couplings, shanks adapters or bits.
Male/Feminine (M/F) rod, pace rod:
M/F drill metal is an substitute to couplings sleeves to include the female component of the threaded connection as an integral part of the drill metal. M/F drill steel gives much more rigid connections and is easier to uncouple and handle. The services daily life also tends to be greater than with individual couplings. The positive aspects of drilling with M/F steel incorporate: easy handling, quicker uncoupling, tighter connections, the prospective to drill straighter holes, and more time provider life.
For extension rod and M/F steel process, the underneath two diverse varieties of warmth treatment method are used to reinforce large pace and effective percussive drill string parts to maximize their performance and trustworthiness. More time metal bigger in diameter, typical extension steel, Hexagonal and round cross sections are offered.
Carburizationis a approach utilized to tougher the total rod floor equally internally and externally to reinforce and lengthen the daily life of the rod.
Large frequency induction is method where only the thread ends of the rod are hardened to lengthen thread life.
