Product Description

     
  Drilling Rod Couplings /lock joint drill pipe coupling
 

The adapter subs/joints are made of 35CrMo or 42CrMo round steel. After rough processing, it is heat-treated. After finishing, the surface is nitrided, which effectively eliminates the failure probability of sticking, fracture and outer diameter cracking. It is more wear-resistant and easy to disassemble. All of equipments adopt precision imported CNC lathes, and the custom-made knives for thread processing, it can not only ensure the tight distance of the thread, but also ensure the precision and interchangeability of the adapter subs/joints.
Advantage:
1. In-house heat treatment ensures optimum surface hardness and case depth 
2. 35CrMO or 42CrMo Steel -high standard 
3. 6 months warranty 
4. Long Life Thread Connection 
5. Reable and wear-resistant.
