Product performance
Strict selection and control of raw materials, and all key parts such as square head of drill pipe adopt forging process, with reliable quality.
The pressure point, key bar, internal key and other parts adopt heat treatment process and optimize the structure of the cloth key to improve wear resistance.
The overall torsional safety factor of the drill pipe is high, and the resistance to pressure and vibration is also higher than the average level, which is more suitable for rock entry requirements.
