Quality
Certifications, test data and traceability
Certifications show the system is in order; factory test data shows the individual tool is good. We supply both kinds of document.
Certifications
| Certification |
|---|
| National Technology-Based SME |
| High-Tech Enterprise |
| Dongying Municipal Key Laboratory |
| Dongying Municipal Industrial Design Centre |
| CNPC QHSE system certification |
| Sinopec QHSE system certification |
Scanned certificates are available on request; the original certificates are the authoritative record.
Factory data and traceability
- Test report ships with the tool — every tool comes with a table of measured values, each item spelled out, not just a line saying "meets the standard".
- Batch traceability — material certificates and heat treatment records for critical parts are filed and kept; the retention period is set out in our quality system documentation.
- Failure analysis report — if a tool fails downhole, we issue a written analysis once it is back at the works, stating plainly whether the cause lies in design, manufacture or use, and where responsibility sits.
