Requirements pickling passivation stainless steel equipment and pipeline put into operation before the start of many large-scale chemical industry, chemical fiber, fertilizer and other devices. Although the device has been carried out in the factory pickling, removing welding slag, oxide, but the process of storage, transportation, installation and inevitably caused by grease, sediment, rust and other pollution, to ensure that devices and equipment commissioning products (especially quality to meet the requirements of chemical intermediates and refined products), to ensure a successful test must pickling passivation. Such as H2O2 production device stainless steel equipment and piping, before going into production must be cleaned, otherwise if dirt heavy metal ions lead to catalyst poisoning. In addition, if the metal surface grease and free iron ions cause the decomposition of H2O2, violent release a lot of heat caused by the fire or even an explosion. The same oxygen pipeline for the presence of traces of oil pollution and metal particles may produce sparks serious consequences.
