The cylindrical equipment that transmits the rotation and pressure movement of the drilling machine to the drill at the end is called TIJ. Rods are one of the most important equipment in the drilling system, they are manufactured from high quality seamless cold drawn steel pipe.

The first pipes downloaded from the installed drilling rig are the Tij pipes. The task of the rod pipes is to drill the borehole with the drills attached to the ends. A few intermediate connection pieces should be added between the drill and the rods, and thick-walled pipes should be added to make weight, both for the connection sequence and for the drill to work properly.
