Sourcing DIN Flange from Linyi Guangnuo Machinery Fitting Group - China Import Guide
Before ordering DIN flanges from this supplier, verify the material certification matches the specified ASTM grade and that the dimensional drawings align with DIN 2503 or ASME B16.5. Confirm that the flanges have undergone hydrostatic testing and that the supplier provides traceable heat batch numbers. Do not accept flanges without test reports if used in pressure systems, as this violates international safety codes.
Lead time is not stated and may vary by order size and material availability. Incoterms are not listed; buyers should confirm whether FOB Qingdao or EXW Linyi applies. Payment terms are not specified - commonly 30% advance with 70% against shipping documents. Packaging must be wooden crate with moisture barrier, and pallets must be fumigated for international shipping. Confirm container loading plans in advance.
Perform incoming inspection for surface defects, dimensional accuracy, and marking legibility. Use a caliper to verify outside diameter and bolt hole spacing. Request a copy of the hydraulic test certificate and cross-check material composition with a portable XRF analyzer if possible. Ensure all documentation includes the supplier’s official stamp and test lab accreditation. Retain samples for third-party lab testing if the flanges will be used in critical infrastructure.
