Sansung rock drilling extension rod are created with high high quality of alloy steel bar and tungsten carbides with excellent use resistance and affect toughness superior, by means of heat therapy so that it can face up to the toughe EPT rock drilling demands, and transmit intense impact strength into the rock with the lea EPT achievable decline of vitality. They are commonly used in all types of mining, drilling, quarrying, engineering, design, drinking water properly drilling, oil checking out industries and so forth.
Extension rod:
EPT names are Extension drill steel, Extension drill rod, and Extension metal, M/Frod (Speed rod), create Hexagonal and spherical cross-sections,Hexagonal rods are far more rigid, heavier and transfer strength much more proficiently,even though increasing flushing. Spherical rods are normally lighter than hexagonal rodsand are typically used in extension drilling apps. With the lengthier metal tending to be bigger in diameter, traditional extension metal is characterizedby duplicate thread on each and every stop of the metal.
Extension rods are manufactured by hollow drill steels, different lengths are accessible from 600mm to 6400mm. This hollow gap are normally named flushing hole, used for transmitting h2o or air for the duration of drilling. And the threads can be used for connecting couplings, shanks adapters or bits.
Male/Feminine (M/F) rod, velocity rod:
M/F drill steel is an different to couplings sleeves to consist of the female portion of the threaded relationship as an integral portion of the drill steel. M/F drill steel provides much more rigid connections and is easier to uncouple and handle. The service daily life also tends to be far better than with independent couplings. The advantages of drilling with M/F metal consist of: effortless dealing with, quicker uncoupling, tighter connections, the possible to drill straighter holes, and for a longer time services lifestyle.
For extension rod and M/F metal process, the under two various sorts of warmth treatment method are employed to bolster large pace and effective percussive drill string factors to maximize their overall performance and dependability. For a longer time metal greater in diameter, standard extension steel, Hexagonal and spherical cross sections are accessible.
Carburizationis a procedure used to harder the complete rod surface area the two internally and externally to improve and increase the daily life of the rod.
Higher frequency induction is approach exactly where only the thread ends of the rod are hardened to lengthen thread existence.
