Before placing an order, confirm the pipe’s material grade (St52, E355, or Q345B equivalent) and verify that the outer diameter, wall thickness, and delivery condition match your project specifications. Request a mill test certificate (MTC) to validate the mechanical properties, including tensile strength, yield strength, and elongation. Ensure the supplier provides documentation for compliance with DIN 1629 or EN 10305-1 standards.
Clarify logistics details, such as packaging (bundled, wooden crates, or custom), lead time for production and shipping, and the Incoterms (FOB, CIF, or CFR) applicable to your order. Confirm the port of loading in Yantai, Shandong, and any export documentation required for customs clearance. Payment terms, such as TT or LC, should be agreed upon before finalizing the purchase.
For quality control, arrange for third-party inspection of the pipes before shipment, focusing on dimensional accuracy, surface finish, and mechanical properties. Request non-destructive testing (NDT) reports, such as ultrasonic or eddy current testing, to detect internal or surface defects. Ensure the supplier provides a material traceability report and any additional certifications required for your industry.
