What aspects should be self-checked during the acid pickling process?

Self-inspection by acid picklers on the steel pipes they are responsible for pickling is a crucial step. Only when everyone strictly controls quality can we ensure that defective and inferior products are not produced or are produced as little as possible. Therefore, acid picklers must self-check the following aspects: whether there are factors harmful to hot-dip galvanizing on the steel pipe surface, such as over-pickling, under-pickling, trapped wires, oil stains, paint scars, bubbles, mud adhering to the surface of the base pipe, acid pickling sludge, iron salts, etc. If any of the above situations exist, appropriate measures should be taken to address them.
