Sansung rock drilling extension rod are created with large good quality of alloy metal bar and tungsten carbides with exceptional use resistance and effect toughness superior, by means of heat treatment so that it can endure the toughe EPT rock drilling demands, and transmit intense influence energy into the rock with the lea EPT possible loss of strength. They are widely utilized in all types of mining, drilling, quarrying, engineering, design, h2o well drilling, oil checking out industries etc.
Extension rod:
EPT names are Extension drill metal, Extension drill rod, and Extension steel, M/Frod (Pace rod), generate Hexagonal and round cross-sections,Hexagonal rods are much more rigid, heavier and transfer energy far more effectively,even though increasing flushing. Round rods are generally lighter than hexagonal rodsand are generally utilized in extension drilling apps. With the more time metal tending to be more substantial in diameter, traditional extension metal is characterizedby replicate thread on every stop of the steel.
Extension rods are made by hollow drill steels, diverse lengths are accessible from 600mm to 6400mm. This hollow gap are usually named flushing hole, employed for transmitting drinking water or air in the course of drilling. And the threads can be utilized for connecting couplings, shanks adapters or bits.
Male/Female (M/F) rod, pace rod:
M/F drill steel is an substitute to couplings sleeves to consist of the woman part of the threaded connection as an integral element of the drill metal. M/F drill metal provides more rigid connections and is easier to uncouple and manage. The service existence also tends to be greater than with different couplings. The advantages of drilling with M/F steel incorporate: straightforward managing, more quickly uncoupling, tighter connections, the possible to drill straighter holes, and more time service daily life.
For extension rod and M/F metal process, the beneath two various sorts of warmth remedy are utilized to improve higher speed and strong percussive drill string parts to optimize their functionality and reliability. Longer metal greater in diameter, standard extension metal, Hexagonal and round cross sections are obtainable.
Carburizationis a method employed to more challenging the entire rod floor each internally and externally to strengthen and prolong the life of the rod.
Higher frequency induction is procedure the place only the thread ends of the rod are hardened to lengthen thread daily life.
