Many large chemical, chemical fiber, fertilizer and other stainless steel equipment and pipeline requiring pickling passivation before production starts.
Although the equipment in the factory has been pickling, in addition to the welding slag and scale, but the hard to avoid in the process of storage, transportation, installation and cause the pollution of grease, mud, sand, rust etc, to ensure that plant and equipment commissioning products (
Especially in chemical intermediates and fine products)
Quality can meet the requirements, to ensure a successful commissioning, pickling passivation must be conducted.
Stainless steel equipment and pipeline, such as H2O2 production unit must be washed before production, or if there is contamination of heavy metal ions will make the catalyst poisoning.
In addition, such as metal surface has a grease trap with free iron ions caused by H2O2 decomposition, intense release a large amount of heat, spark ignition, or even an explosion.
Same for oxygen pipeline exist trace oil and metal particles also may produce a spark and produce serious consequences.
