Readily adsorbed chloride ions in sea water in the heat exchanger passivation film, the oxygen atom squeezed out, and then, and the passivation film to form soluble chlorides cation binding, result in a heat exchanger corrosion of exposed metal surface of a small pits, these pits are called pitting nucleus. These chlorides readily hydrolyze small pit solution pH decreased to make the solution acidic, to dissolve a portion of the oxide film, causing excess metal ions, in order to balance the corrosion pit electrically neutral, the external constant chloride ion migration to the hole, so that the hole is further hydrolyzed metal. This cycle continued corrosion of austenitic stainless steel, faster and faster, and to develop the depth direction of the hole until the formation of the perforation, causing pitting corrosion (pitting). Siping City-energy HVAC Equipment Manufacturing Co., Ltd. is mainly engaged in the transportation of plate heat exchanger; heat exchanger unit; volume heat exchanger; spiral plate heat exchanger, the company set research, development, manufacture, integration services for; radiator information tech enterprises. Company management system, strong technical force, processing equipment, product performance of the domestic advanced level, product quality living in the same industry-leading position. Products sold throughout the country, high-quality products, improve the efficient after-sales service, and establish a good corporate image, so that we win user acceptance and praise. Not only the best companies to better concept, wholeheartedly committed to all aspects have received a steady development. In the "quality first, reasonable price, prompt delivery, integrity and thoughtful" business purpose, dedication and cooperation between the new and old customers, I hope to learn from a total of total of deliberation, Qi development!
