Heavy series Steel Drill Pipes are used for drilling wells with diamond crowns with diameters 76 mm in soils V-IX categories in drillability. The nominal drilling depth according to the assembly of drill pipes can be 1200, 2000 or 3000 m.
Thin-Wall Wireline drill rods designed for exploration drilling for solid minerals. Thin-Wall drill rods reduce string weight up to 30% that allows to increase the depth capacity up to 25% and make economy on energy consumption during drilling.
