Integral Grooved Drill Pipe
Integral Grooved Drill Pipe is a type of drill pipe designed for specific engineering needs, featuring unique structural characteristics and application advantages. Below are its main features and relevant information:
Structural Design: The integral grooved drill pipe adopts an integrally formed design without connections through joints or other means, ensuring higher strength and stability. This design is particularly suitable for working environments requiring high strength and wear resistance.
Groove Design: The outer wall of the drill pipe is machined with specific groove patterns, which help reduce resistance during drilling and retraction. In cases of stuck or buried drills, these grooves assist in powder discharge, effectively resolving issues of stuck drills.
Manufacturing Process: Manufactured using an overall milling process to enhance the wear resistance and overall strength of the drill pipe. Male connectors, female connectors, and the pipe body are typically joined through friction welding, ensuring robustness and stability at the connection points.
Application Range: This type of drill pipe is widely used for directional drilling of long-hole layers underground in coal mines and can also be applied in drilling operations in hard, intact rock formations as well as fragmented coal seams. Additionally, it is suitable for deep hole exploration in soft coal seams and similar rock formations where water flushing and slag removal are less effective, gas emission holes, water probing holes, anti-outburst holes, and interlayer holes.
Technical Parameters: Different specifications of integral grooved drill pipes have varying outer diameters, lengths, pressure resistance capabilities, and other technical parameters to meet different engineering requirements. For example:
