50mm Slip On ANSI B16.5 Forged Steel Flanges , 316 Stainless Steel Flanges

ANSI B16.5 Forged 304/316 Stainless Steel Pipe Flange Slip-On Flange

Neck flat welding flanges are the same as plate flat welding flanges, which are flanges that extend steel pipes, pipe fittings, etc. into the flange and connect with equipment or pipelines through fillet welds.

Sealed form

The sealing surface forms of neck flat welding flanges are:

Raised surface (RF), concave surface (FM), convex surface (M), tenon surface (T), groove surface (G), full surface (FF).

The diameter range of the flat welding flange with neck: DN10~DN600

Advantages

Flat-welded flanges with necks are also flat-welded flanges, because they have a short neck, which increases the strength of the flange and improves the bearing strength of the flange. So it can be used on higher pressure pipelines.

Disadvantages: The cost is higher than the plate flat welding flange, and it is easier to bump during transportation due to its shape.
