Friction welding drillpipe/DTH drill pipe is mainly used for drilling broken, anchor drilling, geothermal air conditioning holes, well and other drilling. The material pipe are purchased from Well-known large-scale enterprises. Pipe body are IU(internal upset) and EU(external upset) at two side. Pipe is connected with joint by friction welding, after this process, the pipe will be tempering treated, the joint of pipe will be upsetted and temperng treatment, and do the nitriding treatment on surface. in this way, thread gluing, breacking, and cracking are avoided effectively. the joint is more wire-resisting, pipes are easy to disassemble. All thread are machined by precision CNC lathe and shaping tools. We have equiped all thread by international standard screw gauge, in this case, our drill pipe is more stable and longer working life.
We can produce API standard threaded drill pipes of different materials, lengths, diameters and wall thicknesses. OEM service is also accepted.

Friction welding drill pipe is mainly used in the drilling blasting hole, guardrail hole, mountain reinfrcement, anchoring and other engineering holes in mines, quarris, high ways, railways and so on.

    Drill pipes that are used in applications such as DTH/ DTHR/ DR basically comprise of a steel pipe with a pin at one end and a box on the other. The job of the drill pipe is to transmit rotational torque and thrust from the drill rig rotary head to down hole drilling tools.

    According to different application, different diameters of drill tubes are needed, basically, smaller DTH hammers need smaller DTH drill tubes, vice versa. Usually we are offering, 60mm, 73mm, 89mm, 102mm, 114mm, 127mm, Usually the threads are standard API connections, like 2 3/8" API REG thread, 3 1/2" API REG thread or API IF thread, etc. According to customers request, from 1000mm to 6000mm length of pipe are available.
