Horizontal Directional Drilling HDD Drill Rod Drill Pipe Features
1. Double Top Structure:
Drill pipe joints adopt the double ledge(double top)structure, such structure can enhance the tightness of joints so that the pressure of the mud could realize non-leakage half way. greatly reduce the resistance to polit drilling and back using this sturcture improves the torional strength of drill pipr so that the box thread will not deformed
2. after optimal design of equal strength and the dispersion of stress to give dull play to the potiontioal of the drill pipr matrial.
3. After forging joints materials, increased matrial density and change the material of fibrous tissue, thereby enhancing its machanical properties.
4.Using joints nitride, phonsphide or copper treatment to ensure thread anti- corrosion, anti-stick, and improve joint surface fatigue resisitance.
5. unsetting& thickening to the tube, improvinig the metallurgical structure and enhancing the impact toughness, ensuring comprehansive mechanical properties and the friction weld seals not be broken.
