Rc Drill Rod - China

Reverse circulation drill pipe, also known as double-wall drill pipe, is a type of drilling tool used for reverse circulation drilling.

It is composed of inner and outer layers of drill pipe (called inner pipe and outer pipe).

An annular gap is formed between the inner and outer tubes.

During drilling, the circulating medium flows from the annular gap of the double-walled drill to the bottom of the hole.

The center hole of the inner tube discharges the circulating medium.

And carry the core sample back to the surface.

The outer tubes of each double-walled drill pipe are connected with threads to ensure the transmission of torque and pressure.

The inner tubes are mostly connected by plugging, which generally functions to circulate the circulating medium, and the plugging joints are equipped with sealing devices.

Reverse circulation drilling can effectively prevent well wall collapse and improve drilling efficiency.

Main features

Roller cone drill pipe products are made of high-quality materials, and the materials are heat treated using multi-functional integrated heat treatment equipment.

All thread processing uses professional CNC processing equipment, and all thread processing and testing are equipped with professional thread gauges that comply with international industry standards.

Therefore, the threads fit closely, maximizing the quality of the thread fit.

Drill pipe welding methods include submerged arc welding or friction welding.

Compared with ordinary welding methods, buried arc welding has deeper penetration and better weld quality after welding.
