Product Name: Ribbed drill pipe
Product Model:
Place of Origin: Shanxi, China
Product Description
The Ribbed drill pipe is designed based on standard geological smooth drill pipes, featuring high-wear-resistant flat spiral blades that are pre-stressed and fully automatically welded. The rib drill pipe body is made from specialized alloy steel pipes (Baosteel R780) for geological applications, while the drill pipe joints are crafted from high-quality 42CrMo alloy structural steel. These components undergo high-pressure forming, vacuum tempering treatment, and friction welding to ensure superior performance and durability.
Features
High-Wear-Resistant Spiral Blades: Designed with a large lead and flat structure, providing minimal rotational resistance and excellent cuttings removal during drilling operations.
Enhanced Durability: Suitable for drilling in various hardness levels and types of formations, significantly reducing the risk of drill pipe seizure and damage to drilling tools, especially in soft coal seams and under impact ground pressure conditions.
Advanced Manufacturing Process: Utilizes high-pressure forming, vacuum tempering, and friction welding to produce a robust and reliable drill pipe.
Applications
Specifically designed for use with fully hydraulic drift drilling rigs in coal mines, this drill pipe is ideal for gas drainage holes, water exploration holes, and anti-outburst holes. It ensures efficient drilling performance in challenging environments.
