Example of quality grading process evaluation items.
| Number | Evaluation items | Level |
|---|---|---|
| 1 | Is there a mature pipe composition design and manufacturing process ? | Level B/Level C |
| 2 | Is a design, manufacturing and service monitoring specification formed ? | |
| 3 | Is the inspection and testing method single, and is there a recognized inspection measurement benchmark ? | |
| 4 | Is a design, manufacturing and service monitoring specification formed ? | |
| 5 | Whether to train the staff on the working conditions and the applicability of the pipe, and whether the staff understand the relevant requirements of the non-API series ? | |
