How to distinguish between loose rust and true rust on spiral steel pipes?

Spiral steel pipes typically cannot be stored in large quantities at the production facility before delivery to the end user, so distributors must keep some inventory on hand. However, most distributors lack spacious indoor storage facilities and rely primarily on outdoor warehouses; leaving spiral steel pipes exposed outdoors inevitably subjects them to wind and sun. So, how can you tell the difference between surface scale and actual rust on spiral steel pipes?

Main Process Characteristics of Spiral Welded Steel Pipes

Processed spiral welded steel pipes offer greater flexibility in diameter and wall‑thickness dimensions, particularly excelling in the production of high‑grade thick‑walled pipes—especially those with small to medium diameters—where they outperform other manufacturing processes. This enables them to meet a wider range of customer requirements for spiral welded pipe specifications.
