Stainless steel flat flanges PN 25, manufactured according to the standard GOST 12820-80 of stainless steel AISI/SS 321 (12Х18Н10Т), are flat flanges that are widely used in various industries for connecting pipelines and pipeline valves.
Material of manufacture: Flanges are made of stainless steel AISI/SS 321 (12Х18Н10Т). This material has high corrosion resistance due to its chromium content (about 18%) and nickel content (about 10%).
Advantages of using flanges made of AISI/SS 321 (12Х18Н10Т) stainless steel
- High strength and durability.
- Corrosion resistance even in aggressive environments.
- Wide range of operating temperatures.
- Versatility of application due to compatibility with various types of pipelines and pipeline valves.
Thanks to their corrosion resistance and ability to operate at fairly high temperatures, flanges made of stainless steel AISI/SS 321 (12Х18Н10Т) find application in the chemical industry, energy sector, food industry, and water supply systems.
