Quick answer: a valve order should arrive with documents that let you trace material, prove the valve was pressure tested, and satisfy your own quality system. This page lists those documents and what each one covers.
Documents that normally travel with the valves
| Document | What it covers |
|---|---|
| Material certificate | Steel grade, heat number and chemical or mechanical results for pressure-containing parts |
| Pressure test record | Shell and seat leakage test results for the tested valves or batches |
| Inspection report | Dimensional and visual inspection against the approved drawing |
| Packing list | Quantities, sizes, marking and tagging as shipped |
| Painting and coating record | Surface preparation and coating system where specified |
Third-party inspection
- Inspection can be attended at our plant by the inspector of your choice
- Inspection can be arranged before shipment, at the agreed hold points
- Test witnessing, marking verification and packing checks can be included in the inspection plan
- Please state the requirement in the inquiry so it is priced and scheduled from the start
What we will publish here
