Water Well Drill Rod 89mm O.D 3 1/2inch For Borehole Drilling
89mm water well drill rod is made of alloy steel, with joints at both ends, and friction welding is used between the joint and the pipe body. It is used to deepen the wellbore, transmit torque, and form a channel for drilling fluid circulation.
Usually the threads are standard API connections, like 2 3/8" API REG thread, 2 3/8" IF thread, etc. According to customers request, from 1000mm to 6000mm length of pipe are available.
| Size(inch) | Outside Diameter | Wall Thickness | thread | length |
| mm | mm | mm | mm | |
| 3 1/2 | 89 | 6 | 2 3/8reg | 1000-6000 |
Water Well Drill Rod is mainly used in various drilling constructions such as borehole water well drilling, geothermal drilling etc.
Process of End-upsetting can meet the API 5D standard
After the heat treatment of thickened pipe, the steel grade can reach G105 or S135.
The forging process and heat treatment of the pipe joint can be up to API SPEC7-1 standard.
Welding area adopts ausforming process. Performance of welding line can reach the API SPEC 7 standard.
Packing: The Water Well Drill Rod is normally packed by wooden boxes, or steel frame.
Delivery: Normally 5-7 days after down payment.
Shipping method: by sea or by train.
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.
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.
