What aspects should be self-checked during the pickling process

Self-inspection by picklers of the steel pipes they are responsible for pickling is a crucial step. Only when everyone strictly controls quality can we ensure that waste and defective products are not produced or are produced minimally. Therefore, picklers must self-check the following aspects: whether the steel pipe surface has issues such as over-pickling, under-pickling, embedded lines, oil stains, paint scars, bubbles, dirt adhering to the surface from the base pipe, pickling sludge, iron salts, and other factors harmful to hot-dip galvanizing. Appropriate measures should be taken if any of the above situations are found.
