High Strength Φ 50 x0. 8M Geological drill Rod For Core /Water Drilling
Adopt high-end friction welding technology, the steel of the friction drill pipe body and joints is made
of high-quality materials, while strictly controlling the metallurgical process, increasing the hardenability
of the steel, ensuring uniform microstructure and mechanical properties and good weldability. performance.
Ensure uniform hardness, increase material toughness and improve fracture toughness of steel. There by
improving the performance stability of the drill pipe, reducing the consumption of the drill pipe, reducing the
cost per ton of coal, and providing convenience for the majority of customers. Recognized by our customers.
