Product Information
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/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. The advantages of
drilling with M/F steel include: easy handling, quicker uncoupling, tighter
connections, the potential to drill straighter holes, and longer service life.
For Extension Rod
and M/F steel process, the below two different types of heat treatment are used
to strengthen high speed and powerful percussive drill string components to
maximize their performance and reliability. Longer steel larger in diameter,
conventional extension steel, Hexagonal and round cross sections are available.
- Carburization
is a process used to harden the entire rod surface both internally and
externally to strengthen and extend the life of the rod.
- High Frequency
Induction is a process where only the thread ends of the rod are hardened to
lengthen thread life.
