German Standard DIN flanges are widely used forged flanges for industrial equipment and pipelines, featuring high precision and compatibility with European industrial systems. Key characteristics and specifications are as follows:
- Core Characteristics: Manufactured via forging process (ensures high mechanical strength, structural integrity, and sealing reliability); compliant with German industrial standards (DIN); suitable for high-pressure, high-temperature, and corrosive industrial environments.
- Material Scope: Carbon steel, stainless steel (e.g., 304L, 316L, duplex grades), alloy steel (forged to meet DIN material requirements, ensuring corrosion resistance and pressure-bearing adaptability).
- Core Specification Series (DIN Number - Pressure Class (PN) - Size Range (DN)):
- DIN 2527: PN6 (DN10–DN500), PN10 (DN10–DN500), PN16 (DN10–DN500), PN25 (DN10–DN500), PN40 (DN10–DN500), PN64 (DN10–DN400), PN100 (DN10–DN350)
