Φ89-70.5-8.466-1000mm geological alloy drill rods

Application fields: drilling, mining, and anchoring in industries such as coal mines, mining, construction, water conservancy projects, railways, highways, bridges, and tunnels. In coal mines, it is mainly used for water exploration, gas detection, and tunnel exploration. Length 0.5m-9.0m (customizable) The drill pipe body uses high-quality geology-specific alloy steel pipes, and the drill pipe joints use high-quality alloy structural steel. Manufacturing is carried out through high-pressure forming, vacuum quenching and tempering, friction welding, and overall surface hardening. Thread processing uses advanced automated equipment to effectively ensure the machining accuracy of each product. The production process of friction welding followed by threading ensures the **coaxiality standard for multiple drill pipe connections during deep hole drilling. Compared with similar products, it offers high bending strength, High rotational torque and smooth operation.
