Marking and packing
Check packing integrity, marking on each item and passport number consistency. Damage to the outer packing is photographed before opening — this preserves the basis for a claim against the carrier or the supplier. Marking should be readable without unpacking: size, GOST, material grade and batch number. Mixed sizes in one package are checked against the packing list before the goods are put away in storage.
Document check
Match the invoice, packing list, mill certificate and product report against the actual batch. Any difference in package count is recorded in the receiving statement with seal numbers and waybills quoted. Document copies can be requested in advance so the receiving checklist is ready before the cargo arrives. Also verify that the certificates belong to this batch and not to a previous shipment.
Measurements and visual check
Spot-check DN, flange thickness and hole diameters; inspect the sealing face for damage and corrosion. Pay special attention to weld-neck hubs and weld ends: nicks and undercuts affect the future weld quality. For large batches, sampling individual items is sufficient when marking and documents fully match. Measured values are worth comparing against the batch report figures.
What to do on discrepancies
Record discrepancies with photos and notify the supply coordinator in writing before installation starts: claims on an uninstalled batch are resolved faster. A batch with discrepancies should not go into installation until a written decision is issued. Agree the claim procedure in advance — who carries out the inspection, within what deadlines and which documents are attached. A pre-agreed procedure reduces crew downtime on site.
