HIGH TENSILE AW 44.5MM / 1.75 INCH CONVENTIONAL DRILL RODS 3M 1.5M FOR MINERAL EXPLORATION

 


In keeping with the high standard of quality expected from a Sinocoredrill Drill product, our drill rods and couplings are no exception.

 

All drill rod products are manufactured from a Cold Drawn, high carbon steel tubing which is equal to or exceeds the minimum tensile strength required by the DCDMA standards.


Use of this high quality steel assures a product that will withstand drilling and driving under the most severe conditions. There is 100% inspection of all threads during the manufacture of drill rod and drill rod couplings.



As required, all thread specifications on drill rod and drill rod couplings meet the thread standards set by DCDMA and will therefore interchange with products manufactured by other DCDMA members.



Description: 


1. Our wireline drill rods are of the highest quality and manufactured to exacting specifications using advancing maching technoogy.

 

2. They are manufactured from seamless steel tube by cold drawn. The material is XJY850/30CrMnSiA which meets the global standard.

 

3. Drill rods are made from quality heat treated materials which ensure superior strength, wear resistance and toughness in the most demanding applications

 

4. Rods and casing are manufactured under stringent industry standards, and are field tested under a variety of conditions.

 

5. All rods are designed to be compatible with the standard DCDMA.


6. Our drill pipes/drill rods got most praise from oversea market.



Mineral exploration is the process of collecting geologic samples in order to locate commercially viable concentrations of minerals like gold, silver, diamonds, limestone, salt, iron ore, and coal
