According to API 5CT,

Grade: K55/ J55 N80 L80 P110

We have advanced technology and complete monitoring tools. Our materials were chosen from the suppliers whiche passed certificate of API. Our internal control standard which is just less 0. 2 times than standard tolerance of API used wet fluorescet magnetic partical inspection equipment for NDT. Coupling thread parameters used Thread single instrument to test. Thread surface used nonstick deduction phosphating solution for phosphatizing. That can make more than 4 times of breakout. All measuring instruments for processing and test are detected by he state- designated agencies in time.
