DIN 2527/DIN2631 Pipe Flanges and Flange Fittings

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) – DIN 2631-2637: – DIN 2631 (PN6: DN10-DN2600), DIN 2632 (PN10: DN10-DN2600), DIN 2633 (PN16: DN10-DN2000) – DIN 2634 (PN25: DN10-DN1000), DIN 2635 (PN40: DN10-DN500), DIN 2636 (PN64: DN10-DN2400) – DIN 2637 (PN100: DN10-DN350) – DIN 2566 (PN16: DN6-DN100), DIN 2642 (PN10: DN10-DN800) – DIN 2573 (PN6: DN10-DN500), DIN 2576 (PN10: DN10-DN500) – DIN 2655 (PN25: DN10-DN500), DIN 2656 (PN40: DN10-DN400) – DIN 2501 (PN10: DN10-DN500), DIN 2673 (PN10: DN10-DN1200) – Other Common Specifications : DIN 2512, DIN 2513, DIN 2514, DIN 2519, DIN 2526 (Type C), DIN 2559, DIN 2558/DIN 2561, DIN 2565-DIN 2569, DIN 2528-DIN 2529, DIN 2638 (general-purpose flanges for equipment/pipelines, complying with DIN standard general requirements) – Application Scope : Widely used in chemical processing, oil refining, boiler systems, power generation, marine equipment, and other industrial fields requiring standardized pipeline/equipment connections, especially in European markets and projects matching German-made equipment.
