South Africa RC Drilling Rod Double Wall Reverse Circulation RC Drill Pipe 6m Length

6m Length RC Drilling Rod Double Wall Reverse Circulation RC Drill Pipe

1、 Basic concepts
The 6-meter long reverse circulation double wall drill pipe is a specialized drill pipe used for reverse circulation drilling, with a length of 6 meters and a double wall design. This type of drill pipe achieves fluid circulation through the annular gap between the inner and outer pipes during drilling, effectively carrying drilling cuttings to the surface.
2、 Structural characteristics
Double wall design: The double wall drill pipe consists of two layers of inner and outer pipe walls. The inner pipe is used to transport the fluid medium required for drilling (such as compressed air or water), while the outer pipe serves to protect and support the inner pipe. At the same time, the annular gap between the inner and outer pipe walls provides a channel for the reverse circulation of the fluid.
High strength materials: Drill rods are usually made of high-strength, corrosion-resistant materials to ensure stability and durability during drilling.
Precision machining: The joint part of the drill rod undergoes precision machining and heat treatment to ensure good connection and sealing performance.

3、 Working principle
During reverse circulation drilling, the fluid medium inside the drill pipe rises to the surface through the annular gap between the drill pipe and the hole wall, while carrying the drill cuttings to the surface. This reverse circulation method helps to reduce the blockage of drilling cuttings in the drill pipe, improve the continuity and stability of drilling.
4、 Application Fields
The 6-meter long reverse circulation double wall drill pipe is widely used in geological exploration, mineral mining, hydrological well drilling and other fields. Especially when obtaining core samples or conducting deep drilling, this type of drill pipe has irreplaceable advantages.
5、 Maintenance and upkeep
Regular inspection: Regularly inspect the drill pipe, including checking whether the pipe wall is worn, whether the joints are loose, etc., to ensure the normal use of the drill pipe.
Cleaning and maintenance: After drilling, promptly clean the drill cuttings and dirt inside and outside the drill rod to maintain its cleanliness and smoothness. At the same time, necessary maintenance should be carried out on the drill rod, such as applying rust proof oil, to extend its service life.
