Features
We adopts famous steel enterprised production of material to produce drill pipe,and heat treatment of materials by using and integrated multi-processing furnace with international standard, Internal thickening technology has carried on the tempering process after friction welding,so the processing quality of drill pipe is stable,reliable,use cycle greatly extended.We can process different length,diameter and wall thickness and material of API standard thread rod,we also can design and manufacture drill pipe according to customers' requirement of the material, length, wa; thickness and connection thread.
drill pipes is mainly used in the drilling blasting hole, guardrail hole, mountain reinforcment, anchoring and other engineering holes in mines, quarris, high ways, railways and so on.It has a long service life.and the y`re also subjected to high bending stress,transferring the percussion energy from rock drill to drilling bit and then into the rock.
Water Well Drill rod oilfield Pipe with thread drill high quality DTH drilling rod
DTH drill pipes play a significant role in all DTH drilling, regardless type of rock, hole depth or drill rig.
