How is the drill pipe length selected?

Drill pipe length is typically selected based on drilling rig specifications. Common standard lengths include 1.5m, 3m, and 6m. Other lengths can be manufactured according to project requirements.

How should RC drill pipes be maintained?

Apply an appropriate amount of thread grease to the connections before each use.
Clean the drill pipes after operation to remove mud, cuttings, and debris.
Inspect pipes regularly and replace or repair damaged or deformed sections in time.
Store drill pipes in a dry, well-ventilated area, avoiding heavy loads and high humidity to prevent deformation and corrosion.
