Common RFQ Mistakes
These points often cause repeated clarification, price revisions or document mismatch.
- Requesting a long weld neck flange price without a drawing
- Omitting overall length or neck outside diameter
- Leaving bore and weld transition unclear for high-pressure service
- Assuming standard ASME dimensions cover a custom high hub design
- Not stating NDT, impact test or third-party inspection before quotation
