Sansung rock drilling extension rod are created with high high quality of alloy steel bar and tungsten carbides with exceptional dress in resistance and affect toughness superior, through warmth treatment so that it can stand up to the toughe EPT rock drilling requires, and transmit intensive impact power into the rock with the lea EPT attainable decline of power. They are extensively used in all varieties of mining, drilling, quarrying, engineering, development, drinking water properly drilling, oil exploring industries and so forth.
Extension rod:
EPT names are Extension drill metal, Extension drill rod, and Extension metal, M/Frod (Velocity rod), generate Hexagonal and round cross-sections,Hexagonal rods are a lot more rigid, heavier and transfer energy far more proficiently,even though increasing flushing. Round rods are normally lighter than hexagonal rodsand are generally utilized in extension drilling programs. With the more time steel tending to be bigger in diameter, traditional extension metal is characterizedby replicate thread on every conclude of the metal.
Extension rods are produced by hollow drill steels, diverse lengths are obtainable from 600mm to 6400mm. This hollow gap are usually named flushing hole, used for transmitting water or air throughout drilling. And the threads can be employed for connecting couplings, shanks adapters or bits.
Male/Female (M/F) rod, velocity rod:
M/F drill steel is an option to couplings sleeves to incorporate the woman portion of the threaded link as an integral element of the drill steel. M/F drill metal offers much more rigid connections and is less difficult to uncouple and handle. The services existence also tends to be greater than with individual couplings. The rewards of drilling with M/F metal include: straightforward managing, a lot quicker uncoupling, tighter connections, the likely to drill straighter holes, and lengthier support life.
For extension rod and M/F steel approach, the underneath two distinct types of warmth treatment are employed to bolster higher velocity and strong percussive drill string components to improve their efficiency and trustworthiness. Lengthier metal greater in diameter, traditional extension steel, Hexagonal and round cross sections are available.
Carburizationis a method utilised to harder the whole rod surface the two internally and externally to strengthen and increase the life of the rod.
Higher frequency induction is approach the place only the thread ends of the rod are hardened to lengthen thread lifestyle.
