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 load-bearing strength of the flange. So it can be used on higher pressure pipelines.
