A blind Flange is a flange which has no bore, and is used to close ends of piping systems. A blind flange also permits easy access to a line once it has been sealed.
Blind Flange manufacturer,C&N supplies Blind Flanges, Industrial Blind Flanges, Blind Fittings in alloy steel, carbon steel, stainless steel, etc.
Pipe flanges that are made to standards called out by ASME B16.5 or ASME B16.47, and MSS SP-44.
They are typically made from forged materials and have machined surfaces. ASME B16.5 refers to nominal pipe sizes (NPS) from ½” to 24″. B16.47 covers NPSs from 26″ to 60″. Each specification further delineates flanges into pressure classes: 150, 300, 400, 600, 900, 1500 and 2500 for B16.5, and B16.47 delineates its flanges into pressure classes 75, 150, 300, 400, 600, 900
Germany and several other countries in the European Union 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 pressfittings. 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 | EN1092-1 Type 11 | DIN 2627 – DIN 2638 |
| Blind Flange | EN1092-1 Type 05 | DIN 2527 |
| Threaded Flange | TEN1092-1 ype 12 | DIN 2558, DIN 2565 – DIN 2569 |
| Flat Flange | EN1092-1 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 | Form B1 |
| Raised Face | Form B1 |
| Raised Fac) | 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 |
