Friction Welding DTH Drill Pipe - DTH Drill Rod
Liaocheng Jinquan Construction Machinery Co.,Ltd can provide DTH
Friction Welding Drill Pipes (DTH Tubes) and Rotary Drilling
Friction Welded Drill Rods (Rotary Pipes) with A.P.I. Connections.
DTH Drill pipe is made of high quality material detected by
spectrograph, impact and tension test. With fully digitized
processing line introduced from Japan with integral heat treatment
equipment. Anti adhesion thread with nitrogen treatment on surface
make it easier for handling. Metallography detection, hardness
test, magnaflux inspection, ultrasonic flaw detection, tensile test
and impact test ensure products quality.
