Import Din Flange — Buy in Bulk from Supplier in China

DIN flanges from Jinan Hyupshin Flanges Co., Ltd. are manufactured to DIN 2573, DIN 2576, and DIN 2633 standards, designed for pressure ratings PN10 to PN40. These flanges feature raised face, flat face, or ring joint sealing surfaces depending on the variant, with bore diameters ranging from DN15 to DN2000 as per the source data. The product is intended for use in industrial piping systems requiring leak-tight, high-integrity connections under moderate to high pressure.

The flanges are produced in carbon steel grades such as ASTM A105 and A350 LF2, with stainless steel options including SS 304 and SS 316 where specified. Material composition follows standard metallurgical tolerances for these grades, with carbon content typically under 0.3% and manganese between 0.6% and 1.65%. Surface finish is machined to Ra 3.2 µm minimum, consistent with typical industrial practice for pressure-containing flanges. No internal coatings or platings are indicated in the source, so these are assumed to be bare or mill-finished unless otherwise requested.

These flanges are commonly purchased by engineering firms and EPC contractors for oil and gas pipelines, chemical processing plants, and municipal water systems. Buyers typically require batch traceability and material test reports. Trade terms include FOB Qingdao or CIF destination, with minimum order quantities negotiated per project. Packaging is in wooden crates with moisture barriers, and lead time is generally 30 to 45 days after deposit confirmation. Custom machining to non-standard dimensions is available upon request.

Jinan Hyupshin Flanges Co., Ltd. is located in Mingshui Zhangqiu, Shandong Province, China, with a registered address at No6, Nanbei Road, Niupai. The supplier is classified as an imported-tier vendor with harbor trust status, indicating verified export experience.
