DIN Pipe Flanges
DIN FLANGES
Most countries in Europe mainly install flanges according to standard DIN EN 1092-1 (forged Stainless or Steel Flanges). Similar to the ASME flange standard, the EN 1092-1 standard has the basic flange forms, such as weld neck flange, blind flange, lapped flange, threaded Flange (Thread ISO7-1 instead of NPT), weld on collar, pressed collars, and adapter flange such as flange coupling GD press fittings. The different forms of flanges within the EN 1092-1 (European Norm Euronorm) is indicated within the flange name through the type.

| Design | According to EN type | According to DIN |
|---|---|---|
| Weld-neck flange | Type 11 | DIN 2627 – DIN 2638 |
| Blind flange | Type 05 | DIN 2527 |
| Threaded flange | Type 12 | DIN 2558, DIN 2565 – DIN 2569 |
| Flat flange | Type 01 | DIN 2573, DIN 2576 |
| Lapped flange | Type 02 & Type 04 | DIN 2641, DIN 2642, DIN 2655, DIN 2656 |
Similar to ASME flanges, EN1092-1 steel and stainless flanges, have several different versions of raised or none raised faces. According to the European form the seals are indicated by different form:
| Form: types of contact faces | DIN EN 1092-1 |
|---|---|
| Without raised face | Form A |
| Raised face (Rz = 160 mechanical turned) | Form B1 |
| Raised race ( Rz = 40 mechanical turned) | Form B1 |
| Raised face (Rz = 16 mechanical turned) | Form B2 |
| Tongue according to DIN2512 | Form C |
| Groove according to DIN 2512 | Form D |
| Male according to DIN 2513 | Form E |
| Female according to DIN 2513 | Form F |
| Female according to DIN 2514 | Form G |
| Male according to DIN 2514 | Form H |
