API 5L PSL1 vs PSL2 Line Pipe
Compare PSL1 and PSL2 ordering details for API 5L line pipe RFQs.
Practical Standard Review
API 5L PSL1 and PSL2 are not interchangeable labels. Buyers should confirm pipe grade, manufacturing route, chemical and mechanical requirements, NDT scope, hydrotest, impact test, traceability, and coating plan before quotation.
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 | API 5L PSL1 and PSL2 are not interchangeable labels. Buyers should confirm pipe grade, manufacturing route, chemical and mechanical requirements, NDT scope, hydrotest, impact test, traceability, and coating plan before quotation. |
|---|---|
| Confirm in RFQ | PSL level, grade, pipe process, OD, WT, end bevel, coating, MTC, and supplementary tests |
| Risk to avoid | Do not quote only X52 or X65 without PSL level when a project specification controls acceptance. |
| 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.
