Sansung rock drilling extension rod are manufactured with large good quality of alloy steel bar and tungsten carbides with superior wear resistance and impact toughness superior, by way of heat treatment so that it can stand up to the toughe EPT rock drilling demands, and transmit intensive affect vitality into the rock with the lea EPT achievable reduction of power. They are commonly used in all sorts of mining, drilling, quarrying, engineering, design, water well drilling, oil exploring industries and so on.
Extension rod:
EPT names are Extension drill steel, Extension drill rod, and Extension metal, M/Frod (Velocity rod), create Hexagonal and spherical cross-sections,Hexagonal rods are more rigid, heavier and transfer power far more efficiently,whilst rising flushing. Spherical rods are usually lighter than hexagonal rodsand are generally used in extension drilling apps. With the longer steel tending to be larger in diameter, typical extension steel is characterizedby replicate thread on every single stop of the steel.
Extension rods are produced by hollow drill steels, different lengths are obtainable from 600mm to 6400mm. This hollow gap are normally named flushing gap, utilised for transmitting h2o or air throughout drilling. And the threads can be utilised for connecting couplings, shanks adapters or bits.
Male/Woman (M/F) rod, pace rod:
M/F drill metal is an substitute to couplings sleeves to contain the feminine element of the threaded connection as an integral element of the drill metal. M/F drill steel offers much more rigid connections and is simpler to uncouple and deal with. The services lifestyle also tends to be much better than with separate couplings. The advantages of drilling with M/F metal incorporate: effortless dealing with, more quickly uncoupling, tighter connections, the prospective to drill straighter holes, and lengthier service existence.
For extension rod and M/F steel method, the beneath two distinct kinds of heat therapy are utilised to strengthen high speed and powerful percussive drill string components to improve their overall performance and dependability. For a longer time steel more substantial in diameter, traditional extension metal, Hexagonal and round cross sections are obtainable.
Carburizationis a method utilised to tougher the whole rod area each internally and externally to strengthen and increase the lifestyle of the rod.
High frequency induction is method the place only the thread finishes of the rod are hardened to lengthen thread lifestyle.
