Which flange standards can YUXIN manufacture to?

We forge and machine flanges to ASME/ANSI B16.5 and B16.47 (Series A & B), EN 1092-1, DIN 2631-2638, JIS B2220, GOST and BS standards, in pressure classes from 150 lb to 2500 lb and PN6 to PN400. Non-standard and drawing-based flanges are also produced.

What documentation is supplied with each shipment?

Every batch ships with an EN 10204 / DIN 50049 3.1B mill test certificate covering heat number, chemical composition, mechanical properties and heat-treatment records. Ultrasonic testing, PMI, hardness, impact and dimensional reports are available on request, together with commercial invoice and packing list for customs clearance.

What is the minimum order quantity and lead time?

Standard carbon steel items in stock sizes ship in 7-15 days. Forged-to-order and non-standard flanges normally require 25-35 days depending on size, material availability and heat-treatment cycle. Low MOQ trial orders are accepted for new distributor partners.

Which materials do you forge?

Carbon steel (A105, Q235B, C22.8, P250GH), low-temperature and alloy steel (LF2, A182 F5/F11/F22, 16Mn), stainless steel (304/304L, 316/316L, 321, F51/F53 duplex) and nickel alloys on project basis.
