Clear standard and pressure rating
Most RFQs need the standard family, flange type, DN or NPS size, PN or Class rating, facing, bore and material grade confirmed before price comparison is useful.

Most RFQs need the standard family, flange type, DN or NPS size, PN or Class rating, facing, bore and material grade confirmed before price comparison is useful.
For European buyers, EN 10204 3.1 material certificates, heat traceability, inspection records, marking photos and certificate references are often as important as unit price.
Hyupshin prepares export packing, labels and shipping documents for distributor stock orders and project batches, with attention to mixed-size shipments and destination port requirements.
European customers may purchase EN 1092-1, DIN, BS 4504 and UNI flanges together with ANSI / ASME B16.5 items. The RFQ review is arranged by standard, type and certificate requirement.
