Specifications:
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.
