Flange RFQ Checklist for Technical Procurement
This working checklist helps a buyer verify that flange material, type, facing, pressure class, size, bore, dimensional route, special machining, testing, certificates, marking, packing, and logistics information are visible before an RFQ is released. It is a disciplined preparation tool, while the governing project specification and drawing remain the source of acceptance requirements.
Working method
Use the checklist to create a technical record before issuing the RFQ.
Working method
Four controls before technical quotation.
