Sansung rock drilling extension rod are produced with high good quality of alloy steel bar and tungsten carbides with excellent dress in resistance and influence toughness exceptional, through warmth treatment method so that it can withstand the toughe EPT rock drilling needs, and transmit intensive impact strength into the rock with the lea EPT attainable reduction of vitality. They are broadly utilized in all varieties of mining, drilling, quarrying, engineering, building, drinking water well drilling, oil discovering industries and many others.
Extension rod:
EPT names are Extension drill metal, Extension drill rod, and Extension metal, M/Frod (Pace rod), make Hexagonal and spherical cross-sections,Hexagonal rods are a lot more rigid, heavier and transfer vitality more effectively,although rising flushing. Spherical rods are typically lighter than hexagonal rodsand are usually used in extension drilling purposes. With the longer metal tending to be greater in diameter, conventional extension metal is characterizedby replicate thread on each finish of the steel.
Extension rods are produced by hollow drill steels, distinct lengths are accessible from 600mm to 6400mm. This hollow gap are normally named flushing gap, employed for transmitting h2o or air in the course of drilling. And the threads can be used for connecting couplings, shanks adapters or bits.
Male/Woman (M/F) rod, velocity rod:
M/F drill metal is an alternative to couplings sleeves to contain the feminine portion of the threaded link as an integral part of the drill steel. M/F drill steel offers far more rigid connections and is simpler to uncouple and deal with. The support existence also tends to be better than with separate couplings. The benefits of drilling with M/F steel incorporate: simple handling, a lot quicker uncoupling, tighter connections, the likely to drill straighter holes, and longer provider lifestyle.
For extension rod and M/F metal approach, the under two different sorts of heat therapy are utilised to strengthen high pace and potent percussive drill string elements to maximize their overall performance and reliability. More time steel larger in diameter, standard extension metal, Hexagonal and round cross sections are accessible.
Carburizationis a process utilised to harder the total rod floor the two internally and externally to bolster and prolong the existence of the rod.
Substantial frequency induction is method exactly where only the thread ends of the rod are hardened to lengthen thread lifestyle.
