Pipes And Tubes Carbon Seamless Steel Black Erw ST37 WELDING Round ST52 Non-Alloy Q195-Q345 ST35-ST52 GB/T 3091-2001 ST4

DTH drill pipe uses high-quality low-carbon steel to ensure good compression and tensile resistance, friction welding to ensure that the adapter and the pipeline are tightly connected as a whole, and the cyclic extrusion-compression ensures the reliability of the pipeline.
The high-pressure air is delivered to DTH through the DTH drill pipe, and the rotation and pressure are transmitted to DTH at the same time.
