ASME B16.9 Pipe Fitting Dimensions
RFQ guide for elbows, tees, reducers, and caps.
Practical Standard Review
Butt weld fitting RFQs should specify fitting type, standard, material, size, schedule, radius, degree, wall thickness match, bevel, coating, and marking.
Himount Steel reviews the ordered standard, grade, product form, dimension tolerance, inspection level, packing method, and shipment route before confirming price and lead time. Final supply always follows the buyer specification and accepted mill test certificate.
Key Ordering Points
| Main comparison | Butt weld fitting RFQs should specify fitting type, standard, material, size, schedule, radius, degree, wall thickness match, bevel, coating, and marking. |
|---|---|
| Confirm in RFQ | ASME B16.9, material grade, fitting type, size, schedule, radius, bevel, and MTC |
| Risk to avoid | For elbows and tees, confirm both run and branch dimensions before production. |
| Documentation | Confirm MTC type, heat number traceability, inspection record, and any buyer approval wording. |
| Next step | Send the project specification or previous PO so Himount Steel can check the supply route. |
Buyer Checks Before Quotation
- Use the project specification as the authority when grade names look similar.
- Confirm product form, size, tolerance, delivery condition, and inspection plan together.
- Ask for comparable references only as RFQ aids, not automatic substitutions.
- Review certificate wording before shipment if the project has strict acceptance rules.
