Din flange
DIN flanges from Qingdao Wanfengyuan Piping Systerm Company Limited are produced to DIN 2573 and DIN 2633 standards, with pressure ratings from PN10 to PN40. The product range includes carbon steel ASTM A105 and stainless steel grades SS 304 and SS 316, with bore diameters from DN15 to DN2000. Flanges feature raised face, flat face, or ring joint sealing surfaces, matching standard industrial configurations for piping connections.
Material composition aligns with ASTM A105 for carbon steel, with carbon content under 0.35%, manganese between 0.6% and 1.05%, and phosphorus and sulfur limits under 0.04%. Stainless steel variants meet the minimum chromium and nickel content for SS 304 and SS 316 as defined in ASTM A182. Surface finish is machined to Ra 3.2 µm, consistent with DIN requirements. No plating or coating is mentioned, so these are assumed to be mill-finished unless specified otherwise.
These flanges are primarily sourced by EPC contractors for oil and gas refineries, chemical plants, and water treatment facilities. Buyers typically require traceable material certificates and hydrostatic testing records. Trade terms include FOB Qingdao or CIF destination, with MOQ negotiable based on project volume. Packaging is in wooden crates with rust inhibitors, and lead time is approximately 35 to 50 days after order confirmation. Custom machining for non-standard dimensions is available upon request.

Sourcing DIN flange from Qingdao Wanfengyuan Piping Systerm Company Limited - China Import Guide
Verify material composition and mechanical properties with certified test reports before accepting delivery. Confirm that the DIN standard referenced (e.g., DIN 2573 vs. DIN 2633) matches your piping system requirements. Request photos of stamped markings and material test reports for each batch. Do not accept flanges without traceable documentation, especially for high-pressure or hazardous service applications.
Confirm Incoterms - FOB Qingdao is standard, but CIF may include unexpected freight charges. Lead time is typically 35 to 50 days after deposit, depending on order volume. Payment terms are often 30% advance, 70% against copy of bill of lading. Ensure the contract includes clauses for non-conforming goods and right to reject shipments that fail dimensional or material checks.
Inspect incoming flanges for dimensional accuracy using calibrated tools. Check bolt hole alignment, face flatness, and surface finish. Confirm that the material grade matches the test report and that no surface cracks or laminations are present. Retain a sample from each shipment for future reference. Request a signed packing list and inspection certificate from the supplier to support import compliance and audit readiness.
