Phosphate pipeline corrosion inhibitor (V730)

During the shutdown cleaning process of the phosphoric acid pipeline, a mixed acid of dilute sulfuric acid and dilute fluorosilicic acid is generally used as the cleaning solution to remove scaling in the system. These cleaning solutions, while cleaning the pipeline and equipment such as graphite heat exchangers, can also cause corrosion to the stainless steel material in the pipeline. The phosphoric acid pipeline corrosion inhibitor V730 is compounded from organic phosphonic acid, polycarboxylic acid sulfonate copolymer, copper-iron corrosion inhibitors, and film-forming substances. It can effectively slow down the corrosion of equipment by sulfuric acid and fluorosilicic acid in the cleaning solution, improving the utilization rate of the equipment.
