3-1/2" Water Well Drill Rod 89mm Water Well Drill Pipe For Borehole
Drilling
Description
Drill pipes is mainly used in the drilling blasting hole, guardrail
hole, mountain reinforcment, anchoring and other engineering holes
in mines, quarris, high ways, railways and so on.It has a long
service life.and the y’re also subjected to high bending
stress,transferring the percussion energy from rock drill to
drilling bit and then into the rock.
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.
We can process different length,diameter and wall thickness and
material of API standard thread rod,we also can design and
manufacture drill pipe according to customers' requirement of the
material, length, wa; thickness and connection thread.

Applications
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.
Features
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
Packing
Packing: The Water Well Drill Rod is normally packed by wooden boxes, or steel frame.
Delivery: Normally 7-10 days after down payment.
Shipping method: by sea or by train.
