RFQ confirmation points
Please confirm standard number, flange type, nominal size, pressure rating, material grade, facing, quantity, certificate requirement and any project drawing before quotation.
Product scope
DIN 2527 blind flange can be quoted in carbon steel, stainless steel or project material grades when the order specification, dimensions and certificate requirements are confirmed.
European buyer focus
Order details to confirm before production
Blind flange inquiries are reviewed against piping service, installation position and required facing.
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.
Procurement guidance
DIN 2527 Blind Flanges quotation notes
DIN 2527 Blind Flanges buying notes
DIN flange inquiries are often connected with older installations, maintenance replacement work, spare-part stock and original project drawings. Buyers may still describe items by DIN 2501, DIN 2527, DIN 2573, DIN 2576 or DIN 2631-2635 even when newer projects use EN references.
A clear DIN RFQ should include the DIN number, PN rating, DN size, sealing face, material and whether the item must match an existing flange. If the buyer is replacing installed parts, photos or old drawings can prevent mistakes in drilling, thickness or facing.
Blind flange details
For blind flanges, facing, thickness, pressure rating and marking are important because the flange is used for closing pipe ends, valves or pressure equipment connections. Certificate and inspection requirements should be listed before production.
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.
How to prepare the RFQ
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.
