Sansung rock drilling extension rod are made with substantial high quality of alloy steel bar and tungsten carbides with superior wear resistance and impact toughness exceptional, by means of heat remedy so that it can face up to the toughe EPT rock drilling needs, and transmit intensive influence strength into the rock with the lea EPT possible reduction of energy. They are widely utilised in all varieties of mining, drilling, quarrying, engineering, development, h2o well drilling, oil exploring industries and so forth.
Extension rod:
EPT names are Extension drill steel, Extension drill rod, and Extension steel, M/Frod (Speed rod), make Hexagonal and spherical cross-sections,Hexagonal rods are far more rigid, heavier and transfer power a lot more proficiently,whilst increasing flushing. Round rods are normally lighter than hexagonal rodsand are generally utilized in extension drilling applications. With the more time metal tending to be bigger in diameter, typical extension metal is characterizedby duplicate thread on each conclude of the metal.
Extension rods are produced by hollow drill steels, different lengths are offered from 600mm to 6400mm. This hollow hole are generally named flushing gap, utilised for transmitting water or air throughout drilling. And the threads can be employed for connecting couplings, shanks adapters or bits.
Male/Woman (M/F) rod, pace rod:
M/F drill steel is an option to couplings sleeves to contain the female part of the threaded link as an integral component of the drill metal. M/F drill metal offers much more rigid connections and is less difficult to uncouple and take care of. The support existence also tends to be far better than with different couplings. The rewards of drilling with M/F metal consist of: straightforward dealing with, faster uncoupling, tighter connections, the possible to drill straighter holes, and longer provider life.
For extension rod and M/F metal approach, the underneath two different varieties of heat treatment method are employed to improve substantial pace and effective percussive drill string factors to optimize their performance and dependability. More time metal greater in diameter, standard extension metal, Hexagonal and round cross sections are available.
Carburizationis a process employed to more challenging the total rod area equally internally and externally to reinforce and extend the life of the rod.
Higher frequency induction is approach where only the thread finishes of the rod are hardened to lengthen thread daily life.
