Slip on Flanges EN1092-1 Type 01 plate flange,ASME B16.5 slip on Flanges

Slip on Flanges

Slip on Flange OR plate flange is a flange which is with an inside diameter that is slightly bigger than the pipe’s outside diameter. These attachments are connected to the pipe via fillet weld at the top and bottom of the flange. Slip on flanges are typically provided with a raised or flat face.

C&N as a professional flange manufacturer,We supply ASME/DIN/EN/JIS flanges etc.

ASME/ASTM Flanges

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

DIN Flange/EN 1092-1 Flanges

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.
