3m Api Reg Dth Drill Rod 89mm Water Well Drill Pipe

3m API Api Reg Water Well Drill Rod Dth Drill Rod 89mm Dth Drill Pipe

As a common downhole drilling tool, drill pipe 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.

3 1/2" Drill rod is widely used for borehole water well drilling. We can supply it with 1m, 2m, 3m, 4m, 5m, 6m etc.

The thread is normally 2 3/8reg or 2 3/8IF. 

The standard wall thickness is 6.45mm.

3 1/2" drill rod is regular products, it is normally in stock.

Water Well Drill Rod is mainly used in various drilling constructions such as gas drainage (mining) holes, exploration and drainage holes, and grouting holes in coal mines with good underground formation conditions. It can also be used in drilling construction in mining, geology, hydropower and other industries.

The rod has high strength and is suitable for both conventional drilling and impact rotary drilling.

1. The Water Well Drill Rod body is welded by friction welding process, the overall mechanical performance of the drill pipe is good, and the service life is long.

2. The Water Well Drill Rod joint has high thread strength and good anti-stick performance.

3. Hardness and wear resistance combined alloy stell,supplied by national top level specialsteel manufacturer

4. Joint of pipe upset forged,Better wear resistance due to increased hardness

5.Joint and pipe are friction-welded,and heat-treated the end-pieces for optimum durability.

6. pipe chemistries are matched to our quench and temper heat treatment processes achieving excellent impact values

IU:Internal upset;EU:External upset
