CASING AND CORE BARRELS|
Casing drill rods are applicable in all types of rotary drilling for fixation of well walls. The rods can be used in geological explorations on solid minerals, water and in other wells.
We also provide core barrels for core sample extraction. The rods undergo process of heat treatment and carbonization.
HEAT TREATMENT AND CARBONITRATION
The body of the rod is heat treated and quenched.
