RC Drill Pipe

Reverse circulation (RC ) drilling represents a fast,economical and efficient way. The RC drilling method will

reduce dramatically both overall drilling costs and impact on the environ-ment. It not only prevents cross

contamination but also enables a large number of sample bags in a short amount of time. The two ends of the pipe

body are internally thickened, tempered after friction welding, quenched and tempered after rough machining of drill

pipe joints, phosphating or nitriding after finishing. It effectively eliminates the failure probability of gluing, broken

buckles, outer diameter swelling and cracking, is more wear-resistant and easy to disassemble.
