Import Din & Uni Flange — Buy in Bulk from Supplier in China

The DIN and UNI flange is a standard piping connection component manufactured to European dimensional standards, compatible with both DIN 2573 and UNI 5893 specifications. These flanges are produced in carbon steel, stainless steel, and alloy materials, with pressure ratings from PN10 to PN100. The product is designed for use in high-pressure fluid systems where leak-free, bolted connections are essential for operational safety.

The flanges are machined to precise tolerances for face flatness and bolt hole alignment. Standard materials include ASTM A105 for carbon steel and ASTM A182 F304/F316 for stainless variants. Surface finish is typically 125 to 250 AARH, suitable for gasket sealing. The product does not include coatings or linings; sealing relies on gasket materials selected for the fluid and temperature conditions. Typical applications require flanges with raised face or ring joint faces, depending on system pressure.

These flanges are purchased by engineering firms in oil and gas, chemical plants, and water infrastructure projects. Buyers often require material traceability, pressure testing, and dimensional inspection reports. Packaging is in steel strapping with plastic wrap and wooden pallets. Export shipments commonly use FOB Qingdao or CIF terms. Minimum order quantities are flexible, but bulk orders typically receive volume discounts on unit cost.
