Product Description

DTH Drilling Tools DTH Drill Pipes DTH Hammers DTH Drill Bits


DTH drill rods (also called as drill tubes or drill pipes) are the mechanism to transmit impact force and rotation torque to DTH hammers and bits, as well as offer pass for the air flow.
                                                                                                                             

In principle, the lighter the rod is, the better it is for the drilling operation. So a thinner one is always preferable than a thicker one if other parameters were the same. 
                        
   
Product specifications:

DTH drill pipes are widely used in mining,water well drilling, geothermal, oil and all kinds of DTH rock drilling, with high quality low carbon steel to ensure good resistance to strengthen and tensile, friction welded to ensure the adapter and pipe connect tightly as a whole set the cyclic extrusion-compression ensure reliable pipe.
