Sansung rock drilling extension rod are created with substantial top quality of alloy metal bar and tungsten carbides with excellent use resistance and affect toughness outstanding, by means of heat therapy so that it can face up to the toughe EPT rock drilling needs, and transmit intense influence energy into the rock with the lea EPT achievable reduction of strength. They are widely used in all varieties of mining, drilling, quarrying, engineering, design, h2o nicely drilling, oil checking out 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 round cross-sections,Hexagonal rods are more rigid, heavier and transfer strength much more successfully,whilst escalating flushing. Round rods are typically lighter than hexagonal rodsand are typically used in extension drilling apps. With the lengthier steel tending to be greater in diameter, traditional extension steel is characterizedby replicate thread on every conclude of the steel.
Extension rods are produced by hollow drill steels, different lengths are accessible from 600mm to 6400mm. This hollow hole are usually named flushing hole, used for transmitting h2o or air for the duration of drilling. And the threads can be employed for connecting couplings, shanks adapters or bits.
Male/Female (M/F) rod, pace rod:
M/F drill steel is an alternative to couplings sleeves to include the female part of the threaded relationship as an integral component of the drill metal. M/F drill steel provides far more rigid connections and is simpler to uncouple and deal with. The provider daily life also tends to be better than with individual couplings. The benefits of drilling with M/F metal contain: effortless managing, quicker uncoupling, tighter connections, the likely to drill straighter holes, and lengthier service life.
For extension rod and M/F steel method, the beneath two diverse kinds of warmth treatment are utilised to reinforce substantial velocity and powerful percussive drill string factors to maximize their functionality and trustworthiness. For a longer time metal greater in diameter, standard extension metal, Hexagonal and round cross sections are offered.
Carburizationis a method employed to tougher the whole rod area both internally and externally to bolster and lengthen the lifestyle of the rod.
High frequency induction is process exactly where only the thread finishes of the rod are hardened to lengthen thread daily life.
