RC Water Well Drill Rod is mainly used for borehole water well drilling and geothermal drilling etc.
The double-wall drill pipe is a full-hole drilling tool, and the hole wall gap is small, so there is no space condition for the broken rock to collapse, and the double-wall drill pipe has a certain supporting effect on the hole wall.
The continuity of the drilling process avoids the damage to the drilling caused by the pressure excitation and suction caused by the frequent lifting and lowering of the drilling tool.
Packing: The Water Well Drill Rod is normally packed by steel frame.
Delivery: Normally 15 days after down payment.
Shipping method: by sea
Hot extrusion machine
Adopt T-connector hydraulic for joints forging, to improve the metallo graphical fibrous tissue and impact toughness. So guarantee the comprehensive mechanical properties of the welding joints.
Heat treatment equipment
To use controllable atmosphere heat treatment equipment. Ensure each workpiece sorbite transfermation more fully, greatly enhance the mechanical properties of joints.
Thread machining equipment
To use CNC machine tool to thread finish machining and thread close tolerances.
Our products are widely used in the scope of mining, water well drilling and exploration, anchor grouting project, side slope protection engineering, oil and gas engineering, underwater rock drilling & blasting operations of seaport channel, hydropower project, national defense projects, etc.
We own the most advanced pipe production line in China.The technology of heat treatment product line has achieved to the world-class leading levels, we have 200T Friction Welding Machine is the largest model welder, the largest welding capacity can reach drill rod of 200mm OD.
The tube body upsetting technology has achieved the advanced level.Thickening of the anti-extrusion molding of pipe end technology can make the transition zone of internal and external upsetting reach the length to 200mm above.
And the one-piece drilling upsetting technology is more outstanding.
