Acceptable Welded Pipe Quality with Packaging Issue Resolved
Ordered 10 tons of ERW pipe, 219.1mm OD × 8.0mm wall, mixed lengths of 6m and 12m, for resale to a construction client in Indonesia. The mechanical properties and dimensional accuracy were within specification — tensile strength at 421 MPa and OD tolerance at ±0.4%. However, on arrival at Singapore port, we found that roughly 15% of the 12-meter pipes had damaged end caps and some minor denting at the pipe ends from insufficient bundle padding. We raised this with the sales team and they provided a credit note within 48 hours and confirmed improved packaging for future orders. The material quality is acceptable but packaging for longer lengths needs attention. Will trial one more order to see if the improvement holds.
