Friction-welded Drill Pipe (Down-the-hole drill rods, external flat drill rods) Primarily used in rock drilling and anchoring. Drill Kong, geothermal air conditioning Kong , well drilling, and more. Tube body All materials are sourced from well-known, large-scale domestic steel enterprises. Pipe Body Two The end features an internally thickened process, followed by tempering treatment after friction welding. Drill pipe joint After rough machining, tempered heat treatment is applied; following precision machining, surface nitriding is performed—effectively preventing galling. Fracture surface, outer diameter Failure probabilities such as bursting , more wear-resistant and easy to disassemble. All Adopt Precision-imported CNC lathes equipped with custom-molded cutting tools for threading operations. All threads are equipped with thread gauges that meet international standards, therefore Production The drill rods feature stable and reliable quality, significantly extending their service life.

We Both is possible Production Different Materials, Length, diameter 、 API standard threaded drill pipes with wall thickness can also be manufactured according to customer-specified materials, lengths, and wall thicknesses. 、 Thread Come Custom drill rods.
