Stainless steel flanges have excellent metal properties and strong corrosion resistance. Commonly used in steel structures. Stainless steel flanges also become acid resistant stainless steel flanges, and the metal surface becomes smooth. This is not easy. Due to its oxidation by air, it is commonly used in high-pressure water pipes and corrosive pressure pipes, and stainless steel flanges have excellent performance.
1. Corrosion resistance: Stainless steel flanges have strong corrosion resistance and can be used for a long time in various corrosive media, such as acid, alkali, salt, etc
2. High temperature performance: Stainless steel flanges have good stability and heat resistance in high temperature environments, and can withstand high temperature without deformation or damage.
3. High strength: Stainless steel flanges have high strength and stiffness, which can withstand high pressure and impact forces, ensuring the safe operation of the pipeline system.
4. Good sealing performance: The stainless steel flange adopts a tight connection method, which can effectively prevent leakage and ensure the safety of fluid transmission.
5. Wear resistance: The surface of stainless steel flanges is smooth and has high hardness, which has good wear resistance and can reduce leakage and faults caused by wear.
6. Easy maintenance: Stainless steel flanges are easy to maintain, not prone to rusting, easy to clean, and can extend their service life.
Firstly, as a metal material, it reacts with air in a humid environment, thereby changing the performance of the original metal. However, the flange is passivated by an oxidant, and the tough and high-density chromium rich surface oxide protective film Cr2O3 effectively prevents further oxidation reactions. Other metal pipes, such as galvanized water pipes and copper pipes, have low passivation ability, which is the main reason why the corrosion resistance of galvanized pipes is much lower than that of stainless steel pipes. In this way, the corrosion resistance of stainless steel flanges will not corrode uniformly like carbon steel, and there is no need for protective coatings during use. Due to its stainless steel nature, it exhibits excellent corrosion resistance in terms of water content, temperature, pH, and hardness.
Stainless steel butt welding flanges are suitable for pipelines with significant pressure and temperature fluctuations, as well as high-temperature, high-pressure, and low-temperature pipelines. They can also be used for pipelines transporting expensive media.
