Product Description:
Extension rod, other names are Extension drill steel, Extension
drill rod, and Extension steel, M/F rod ( Speedrod ) , Produce
Hexagonal and round cross sections, Hexagon rods are more rigid,
heavier and transfer energy more efficiently, while increasing
flushing. Round rods are generally lighter than hexagonal rods and
are normally used in extension drilling applications. With the
longer steel tending to be larger in diameter, conventional
extension steel is characterized by a duplicate thread on each end
of the steel.
Male / Male rod, Male/Female (M/F) Rod -Speed rod
M/F drill steel is an alternative to couplings sleeves to include
the female part of the threaded connection as an integral part of
the drill steel. M/F drill steel provides more rigid connections
and is easier to uncouple and handle. The service life also tends
to be better than with separate couplings.
For Extension Rod and M/F steel process, the Carburization of heat
treatment are used to strengthen high speed and powerful percussive
drill string components to maximize their performance and
reliability.
Carburization is a process used to harden the entire rod surface
both internally and externally to strengthen and extend the life of
the rod.
