Weld Neck Flanges

Weld neck flange is normally referred to as the “high hub” Flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the Flange. The welding neck flange is the best designed butt-welded flange of those currently available because of its inherent structural value. It is expensive because of the design.

For the face of flange,They are made to standardized dimensions and are typically “flat face”, “raised face”, “tongue and groove”, or “ring joint” styles, although other obscure styles are possible.

Weld neck Flange manufacturer,C&N supplies Blind Flanges, Industrial weld neck Flanges,  alloy steel, carbon steel, stainless steel, 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.

GOST 33259 Type 11 Weld neck Flanges

 

Similar to ASME flanges, EN 1092-1 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
