Supply notes

DIN 2634 PN25 Weld Neck Flanges for European buyers

Product scope

DIN 2634 PN25 weld neck flange can be quoted in carbon steel, stainless steel or project material grades when the order specification, dimensions and certificate requirements are confirmed.

RFQ confirmation points

Please confirm standard number, DN size, pressure rating, material grade, facing, quantity, certificate requirement and any project drawing before quotation.

European buyer focus

Order details to confirm before production

Application

Weld Neck flange inquiries are reviewed against piping service, installation position and required facing.

Pressure rating

State PN rating clearly, especially PN10, PN16, PN25 or PN40 for regular European distributor orders.

Material range

Common RFQs include carbon steel, low-temperature steel and stainless steel grades. Attach the project grade when it differs from regular stock items.

Facing and finish

Confirm RF, FF, RTJ, galvanized finish, black paint, anti-rust oil or project-specific surface protection before quotation.

Certificate support

Mention EN 10204 3.1, PED, AD 2000, UKCA, PMI, NDT or third-party inspection requirements in the RFQ.

Packing

For European shipment, state pallet, wooden case, label, marking and mixed-size packing requirements early.

Procurement guidance

DIN 2634 PN25 Weld Neck Flanges quotation notes

Replacement and legacy standard supply

DIN 2634 PN25 Weld Neck 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.

Type confirmation

Weld Neck flange details

For weld neck flanges, the bore, pipe schedule, welding neck dimensions and pressure service should be stated clearly. These details affect machining and inspection, especially when the buyer needs WNRF, WNFF or RTJ execution.

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.
