The corrosion resistance of stainless steel flanges is optimal in a variety of raw materials
Shanxi Haokun Flange Co. produces carbon steel, stainless steel and alloy steel flanges.Carbon steel flange is weak corrosion resistance because carbon steel contains less alloy elements, stainless steel contains more chromium nickel metal, with strong corrosion resistance in various pipe stainless steel flange corrosion resistance is the best, because stainless steel flange can passivation with oxidizer, on the surface of a tough and thick chromium rich oxide protective film Cr2O3, effectively prevent the further oxidation reaction, stainless steel flange will not occur uniform corrosion like carbon steel, used without protective coating.Carbon steel flange surface should be painted with yellow paint, black paint and Anti-rust oil treatment.Stainless steel flange has the resistance to atmospheric oxidation-rust, but also corrosion resistance in acid, alkali, salt medium-corrosion resistance, but its corrosion resistance is changed with its steel chemical composition, mutual state, use conditions and environmental medium type, such as 304 steel pipe, in dry and clean atmosphere, has absolutely excellent rust resistance, but it is moved to the seaside area, in the sea fog containing a large amount of salt, will soon rust, stainless steel flange corrosion in a certain medium environment, the stainless steel flange wall thinner, local pits And hemp point.Haokun company has an independent national laboratory and various testing and inspection equipment, and can carry out various testing and identification of the company and external enterprises.The detection method is leakage and ultrasonic detection method to test whether stainless steel flange corrosion.Can all the stainless steel flanges be corroded in a certain medium environment?The answer is certainly not,316 Raw materials is one of them, therefore, not any kind of stainless steel flange, in any environment can be corrosion resistance, no rust.
Customers in the purchase of stainless steel flange, the product technical requirements and installation conditions are very clear, they choose the most stainless steel raw materials are decided according to the technical requirements.Haokun company, as a professional supplier of various raw material flanges, should produce flange products according to customer requirements.
