Description

3 1/2'' Reverse Circulation Drill RC Drill Pipe/Drill Pipe


Product Description:

The double-wall drill pipe is conducive to drilling through complex formations. The circulation of compressed air in the double-wall drill pipe is like a closed-circuit circulation system. Even if it encounters an old hole or a karst cave, once the drill tool reaches the bottom of the hole, the normal circulation will resume immediately. , which cannot be achieved in conventional drilling methods.
