None Excavating Drill Pipe
Main features for drill rod:
•Equal intensity and design on stress distribution
•Processing within azotic environment Quality Assurance System:
•The pipe material is conformed to AP Standard and passed backset defecting test.
•The joint is processed by high-precision digital machine, meeting a demand for SY/T5290-2000.
•The shank of joint is processed within azotic environment.
•The digital controlling system is used on quality check of fillet weld, heat-treatment after welding.

Remark：
The joint of drill rod with high air pressure is machined by CNC, and pin is abrasive and anti-impact after being processed within azotic environment,
The materials of drill rod is carbide steel welding with joint after heat-treatment, to ensure high connection and capability, being sealed strictly, and long service time.
