AQ BQ NQ HQ PQ Wireline Drill Rods Drill Rod/Core Drill Rod/Drill Rod For Mineral Exploration
Sinocoredrill wireline drill rods are made of special geological steel pipe with high strength and toughness which is processed by high-precision CNC lathe and molding tools. The drill rod thread is tested by special thread gauge, and the thread part is specially strengthened.
1. Our drill rods are of the highest quality ,are 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 demand in 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 other rods manufactured to the standard DCDMA
