Horizontal Directional Drilling HDD 3M 73mm drill pipe/ Drill rod
1. Double Top Structure:
drill pipr 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 structure improves the torional strength of drill pipr so that the box thread will not be 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.
To guarantee premium quality product, all products material is sourced from Shanghai Baosteel specially developed hot rolling high strength alloy structure tube for oil and gas drilling tools without considering about high cost.
This material uses external refining and vacuum degassing technology with even composition and high purity. The lowest content of harmful chemical elements such as phosphor and sulfur is reached.
Non destructive test is performed according to NDT standard Level 2 with combination of eddy and ultrasonic to guarantee material quality without any defect.
Each of drill pipe is treated by shot peening. After shot peening treatment, surface of drill pipe and thread gets residual pressure stress. This stress can improve drill pipe anti-fatigue service life. Shot peening treatment on thread can help thread compound adhering to thread. Thread service life is improved.
