OD 140mm API Standard DTH Drill Rod for for Open Hole Drilling and
Geothermal Wells
Product Description:
Traditionally, the threads and the joint between the tube and the
end-pieces are vulnerable. To combat the problem, we've
friction-welded the joints for maximum strength and heat-treated
the end-pieces for optimum durability.
Premium alloy steel made joints,strictly controlled heat treatment
process and standard API thread processing technology;we pay high
attention to all these ignored details to ensures a long service
life,stability and thread durability.
We can also provide related products DTH hammers, ODEX system,
symmetrix systems, slide block drilling systems, etc and DTH
drilling pipes for various thread API REG, API IF, BECO, etc

Product Advantage:
1. Reliable wall thickness
2. Less ovality. Less risk of eccentric wear.
3. Better quality of the friction weld, less risk of concentricity
of welding.
4. Better wear resistance due to increased hardness.
5. Reliable weights max 2-3% variance.
6. Less risk of damage to the tube from the straightening
operation.
7. An overall weight reduction of our DTH tube assortment.
