Specification-led procurement

Duplex 2205, S32750, and S32760 must be compared against the actual service

The alloy family, UNS, material standard, fabrication route, inspection, and acceptance criteria should be reviewed together. No grade is universally superior; actual process, temperature, chlorides, pressure, design, and project specification govern selection.

Nigeria procurement FAQs

Answers for a technically complete request.

These answers guide RFQ preparation. They do not replace project engineering, applicable standards, or purchase-order requirements.

How should an RFQ identify an LNG, refinery, or offshore requirement for Nigeria?

State the final Nigeria delivery point and operating context with the component line data, inspection plan, documentation, packing marks, and receiving restrictions. A location reference does not replace the project specification or establish a supply or approval claim.

Does this page state local stock, a warehouse, or an office in Nigeria?

No. This page supports procurement for Nigeria and does not state that RTI has an office, warehouse, stockyard, local stock, or manufacturing facility in the country.

Which grades can be named in a duplex flange RFQ?

State the required grade and UNS, for example Duplex 2205, S32750 / 2507, or S32760, with the approved material-product standard and project acceptance basis.

When should IGC be specified?

State the applicable project or material requirement, test method where identified, acceptance criteria, records, and release requirements.
