Characteristics and structural shapes of stainless steel flange

　　Stainless steel flange connection is the most basic and common way of connection in various containers and process pipelines. Because of the requirements of production process or the convenience of manufacturing, transportation, installation and maintenance, the connection of the container and process pipe often uses the detachable structure, that is, the ANSI 900lb Stainless Steel Flange connection. It has good connection strength and tightness, and is widely used in the size range. Therefore, the Stainless Steel Flange connection is widely used in the vacuum salt making enterprise because of J. The medium in the vessel and pipe is sodium bromide solution (i.e. bittern). It has strong corrosiveness. Although carbon steel flanges have high strength and good plasticity and cutting property, they have poor corrosion resistance. After a month, a large area of corrosion will occur. Six months later, there was a large area of perforation. Cause the leakage of the medium. If stainless steel flange are used: one is more expensive. Stainless steel (ICr18Ni9Ti) flat flanges are about 3-5 times as high as carbon steel flanges; two is a relatively high requirement for welding technology, such as poor waving, which can easily lead to cracks in the joints: three the present use of stainless steel flanges can reduce the plasticity, toughness and punching properties of the material because of the existence of titanium carbide in the steel. The stainless steel flange are easily broken by bad use.
