Sansung rock drilling extension rod are created with higher top quality of alloy metal bar and tungsten carbides with superior dress in resistance and influence toughness superior, by means of warmth remedy so that it can face up to the toughe EPT rock drilling requires, and transmit intense effect vitality into the rock with the lea EPT feasible loss of energy. They are commonly utilized in all varieties of mining, drilling, quarrying, engineering, construction, water well drilling, oil exploring industries etc.
Extension rod:
EPT names are Extension drill metal, Extension drill rod, and Extension metal, M/Frod (Pace rod), generate Hexagonal and spherical cross-sections,Hexagonal rods are much more rigid, heavier and transfer energy a lot more effectively,while escalating flushing. Spherical rods are normally lighter than hexagonal rodsand are generally utilised in extension drilling applications. With the more time steel tending to be more substantial in diameter, typical extension steel is characterizedby duplicate thread on each and every end of the metal.
Extension rods are created by hollow drill steels, distinct lengths are offered from 600mm to 6400mm. This hollow hole are usually named flushing gap, utilised for transmitting drinking water or air for the duration of drilling. And the threads can be utilised for connecting couplings, shanks adapters or bits.
Male/Woman (M/F) rod, pace rod:
M/F drill steel is an different to couplings sleeves to contain the female component of the threaded connection as an integral portion of the drill steel. M/F drill steel gives much more rigid connections and is simpler to uncouple and take care of. The service daily life also tends to be greater than with separate couplings. The rewards of drilling with M/F steel incorporate: effortless managing, faster uncoupling, tighter connections, the prospective to drill straighter holes, and more time provider daily life.
For extension rod and M/F metal method, the beneath two distinct sorts of warmth treatment method are used to reinforce high velocity and effective percussive drill string parts to improve their overall performance and reliability. Lengthier metal larger in diameter, traditional extension metal, Hexagonal and round cross sections are available.
Carburizationis a method employed to harder the total rod surface equally internally and externally to reinforce and extend the life of the rod.
High frequency induction is approach in which only the thread finishes of the rod are hardened to lengthen thread lifestyle.
