Coated steel pipe should be checked before loading because many problems happen during handling, not during pipe making. The first check is the coating surface. Workers should look for cuts, crushed spots, bubbles, or places where the steel can be seen. The second check is the pipe end. If the end is grooved, threaded, or flanged, the sealing face and coating edge should be clean.
The third check is the mark on each bundle. Size, wall thickness, coating type, quantity, and batch information need to match the packing list. For long-distance shipping, wooden pads or soft belts are better than direct contact with sharp steel edges. Pipes should not be dragged on the ground, because one small scratch can become a rust point after storage. Photos before shipment are also useful. They help both sides confirm surface color, bundle shape, and loading condition before the truck or container leaves the yard.
