What's API Standard Thread Type Drilling Pipe?
Roschen DTH drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe. The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.
API Standard Thread Type Drilling Pipe Features:
1. Applicable hard,very hard and medium soft rock formations.
2. Reliable quality, long service life, rare abnormal breakage during service life.
3. Good flushing effect to ensure high drilling rate
4. Strict quality warranty and compensation rules
