Typical UNI references include UNI 2253, UNI 2254, UNI 2276, UNI 2277, UNI 2278, UNI 2280, UNI 2281, UNI 2282, UNI 2283, UNI 2284, UNI 6083, UNI 6084, UNI 6088, UNI 6089, UNI 6090, UNI 6091, UNI 6092, UNI 6093, UNI 6094 and UNI 6095.
UNI inquiries should include the exact standard number, PN rating, nominal size, material grade, flange facing and required documentation.
UNI flange inquiries are reviewed by standard, pressure rating and project use.
State PN rating clearly, especially PN10, PN16, PN25 or PN40 for regular European distributor orders.
Common RFQs include carbon steel, low-temperature steel and stainless steel grades. Attach the project grade when it differs from regular stock items.
Confirm RF, FF, RTJ, galvanized finish, black paint, anti-rust oil or project-specific surface protection before quotation.
Mention EN 10204 3.1, PED, AD 2000, UKCA, PMI, NDT or third-party inspection requirements in the RFQ.
For European shipment, state pallet, wooden case, label, marking and mixed-size packing requirements early.
UNI flange pages support Italian standard references used in distributor stock, maintenance work and regional European projects. Plate flanges under UNI 2276, 2277 and 2278 and weld neck flanges under UNI 2280-2284 should be quoted with the exact UNI number rather than only a general description.
Italian and nearby European buyers often care about dimensional matching, material certificate, finish and repeat availability. The RFQ should include the UNI series, DN size, PN rating, material and whether the flanges are for stock or a named project.
For this flange type, the safest quotation route is to send the standard, size range, pressure rating, material grade, facing, quantity and any drawing notes together in one RFQ. This gives the sales and technical team enough information to check the order before pricing.
For European buyers, the quotation is stronger when documentation requirements are stated at the beginning: EN 10204 3.1 certificate, PED or AD 2000 references, UKCA notes, third-party inspection, PMI, NDT, marking photos or packing photos. This avoids revising the price after the technical review.
Hyupshin recommends sending the RFQ as a table when several sizes are involved. Separate each standard, type, pressure rating and material grade into its own line, then add quantity, destination port and required delivery time. This format is easier for European importers, distributors and project suppliers to compare and repeat in future orders.
If the order is urgent, mark which sizes are needed first and whether partial shipment is acceptable. For repeat distributors, previous purchase records or customer part numbers can be added to the message field so the specification can be matched more quickly.
