Speaking of sulfuric acid is not unfamiliar to everyone, mentioning it we may think of its corrosive properties, but do you know? Sulfuric acid is one of the important basic chemical raw materials, mainly used in the manufacture of phosphate fertilizer and inorganic chemical raw materials, followed by as chemical raw materials are widely used in the smelting of non-ferrous metals, petroleum refining and petrochemicals, rubber industry, as well as pesticides, pharmaceuticals, printing and dyeing, leather, steel industry, such as acid washing. Sulfuric acid production requires the use of heat transfer equipment, and the more widely used is the sulfuric acid industry plate heat exchanger.
Since sulfuric acid is very corrosive, then the equipment used for its production needs to have the corresponding anti-corrosion properties, with the change in concentration of sulfuric acid will show the oxidizing and reducing properties. Concentrated sulfuric acid tends to be oxidizing, dilute acid tends to be reducing, and its corrosiveness increases sharply with the increase in temperature. So the sulfuric acid industrial plate heat exchanger on the material requirements will be very high, to have both oxidation resistance and reduction resistance.
Here is a tip is that after a period of time you can switch the acid inlet and water outlet, which can make the service life of the sulfuric acid industrial plate heat exchanger longer. There is also the case of avoiding water breakage when using the equipment to avoid damage to the equipment due to the increase in material wall temperature.
Therefore, in summary, a high-quality sulfuric acid industrial plate heat exchanger must have resistance to oxidation and reduction, but also to have the corresponding anti-corrosion properties. Then in the selection of the need to select a professional heat exchanger manufacturers, because the general manufacturers in the quality of materials on this basic requirement is difficult to pass.
Qingdao Reapter heat exchanger manufacturers plate gaskets are all acid, alkali and high temperature resistant imported materials, and in strict accordance with higher than the international standard process development and design production, each link of production can be traced.
