1. Our wireline drill rods are all manufactured by CNC machines under DCDMA standard. They're made of high quality alloy steel with heat-treated.  We also can produce various sizes of casing tubes. 

2. Drill pipes will be manufactured from seamless steel tube by cold drawn.The material is XJY850/30CrMnSiA which is one of the best material for geological drilling in China. 
 
3. Coring rods are crafted from quality heat treated materials ensuring superior wear resistance, strength, 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 other rods  manufactured to DCDMA
