HDD Integrated Drill pipe

1. HDD Integrated Drill pipe

1. Material selection-with API standard and reliable performance.

2. The twice thickening molding technology of pipe joint makes the transition zone very stable and smooth which tremendously reduce the resistance of mud through the pipe.

3. With National initiative integral drill rod and intermediate-frequency heat treatment technology make this kind of product have the higher Mechanical Properties than the similar products.

4. Be treated by liquid nitrogen treatment process, the joint thread is deeper than the traditional processing technology which greatly prolong the service life of products.
