DIN 2576 Plate Flange Specification
DIN 2576 is superseded by EN 1092-1 Type 01 PN10, but it remains in wide industrial use, especially for legacy systems and global applications.
DIN 2576 is a German industrial standard that specifies the dimensions, tolerances, and requirements for plate flanges (also known as plain flanges or Type 01 flanges) designed for welding to pipes, with a nominal pressure rating of PN10 (10 bar).
Standard Name: DIN 2576 – Circular flanges made of steel – for welding – PN10
Flange Type: Plate Flange (also called Type 01 according to EN 1092-1)
Nominal Pressure Rating: PN10 (10 bar / 145 psi)
Connection Type: Butt weld (for welding with pipes)
Face Type: Flat Face (FF), no raised face
Application: Low to medium pressure systems (e.g., water, air, non-hazardous fluids)
Testing & Certification
- Dimensional inspection per DIN standard
- Hydrostatic pressure testing (if required)
- Material certificates: EN 10204 3.1 or 3.2
- CE marking under PED (for pressure applications in Europe)
