DIN Flange

DIN Flange

DIN flanges are a critical component in piping systems, offering a standardized and reliable method for connecting pipes, valves, and other equipment. These flanges adhere to stringent German and European standards, ensuring consistency, quality, and compatibility across various industries.

DIN flanges are widely used in industries such as oil and gas, petrochemical, power plants, food processing, pharmaceuticals, and water treatment. They are known for their durability, corrosion resistance, and ability to withstand high pressures and temperatures.

DIN Flange Materials

DIN flanges are manufactured from a variety of materials, each selected based on the application’s requirements, such as pressure, temperature, and corrosion resistance. Common materials include:

  • Carbon Steel (e.g., DIN 1.0425, DIN 1.0570) – Offers excellent strength and affordability but requires protection against corrosion.
  • Stainless Steel (e.g., DIN 1.4301, DIN 1.4404) – Provides superior corrosion resistance and is widely used in chemical and food industries.
  • Alloy Steel (e.g., DIN 1.7335, DIN 1.7380) – Enhances performance under high temperatures and pressures.
  • Duplex & Super Duplex Stainless Steel (e.g., DIN 1.4462, DIN 1.4410) – Combines high strength with excellent corrosion resistance.
  • Copper Alloys (e.g., DIN 2.0882, DIN 2.0857) – Used in marine and desalination industries for resistance to seawater corrosion.
  • Nickel Alloys (e.g., DIN 2.4856, DIN 2.4375) – Ideal for extreme environments such as chemical processing and aerospace.

DIN Flange Dimensions & Standards

DIN flanges are standardized to ensure global compatibility and ease of interchangeability. The most commonly used DIN standards include:

  • DIN 2501 – General flange dimensions and pressure ratings.
  • DIN 2527 – Blind flanges.
  • DIN 2576 – Slip-on flanges.
  • DIN 2631-2638 – Weld neck flanges with various pressure ratings.
  • DIN 2641-2642 – Lap joint flanges.
  • DIN 2655-2656 – Loose flanges with weld-on collars.
  • DIN 2565-2567 – Threaded flanges.
