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.

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.

Design According to EN Type According to DIN
Weld Neck Flange EN 1092-1 Type 11 DIN 2633 – DIN 2632
Blind Flange EN 1092-1 Type 05 DIN 2527
Threaded Flange EN 1092-1 ype 12 DIN 2558, DIN 2565 – DIN 2569
Flat Flange EN 1092-1 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
