46. What aspects are covered in the self-inspection process for pickling?

Self-inspection by pickling workers is a critical step in quality control for their steel pipes. Only through collective quality management can we ensure minimal or no defective products. Therefore, pickling workers must inspect the following aspects: whether the steel pipe surface shows signs of over-pickling, under-pickling, wire sticking, oil stains, paint scars, bubbles, dirt adhering to the base pipe surface, or the presence of harmful elements such as pickling sludge and iron salts that may affect hot-dip galvanizing. If any of these issues are detected, appropriate corrective measures should be implemented.
