Advantages: Necked flat welding flanges are also classified as flat welding flanges, as they have a short neck, which improves the strength of the flange and improves its load-bearing capacity. So it can be used on higher pressure official roads. Disadvantages: Compared to plate type flat welding flanges, they have a higher cost and are more prone to collision during transportation due to their shape characteristics.

20The full name of flat welded flange with neck is flat welded steel pipe flange, which is a flange that extends steel pipes, fittings, etc. into the flange and connects it to equipment or pipelines through fillet welds.
Chinese name: Flat welding flange with neck Foreign name: Slip-on Manufacturing process: Forged flange material: Carbon steel, molybdenum steel, 304, etc. Function: Parts that connect pipes to each other Applicable nominal pressure: Not exceeding 2.5MPa
Function: The neck flat welding flange, like the plate flat welding flange, is also a flange that extends steel pipes, pipe fittings, etc. into the flange and connects it to equipment or pipelines through fillet welds. Sealing form: The sealing surface forms of the neck flat welding flange include: raised face (RF), concave face (FM), convex face (M), tenon face (T), groove face (G), and full face (FF). The diameter range of the neck flat welding flange is DN10~DN600. Flange material: carbon steel, molybdenum steel, 304, 316, 304L, 316L, 321, 347, CF8C. Common manufacturing standards in China include: national standards of the National Standards of the People's Republic of China; GB/T 9116-2010 Hubbed slip on welding steel pipe flanges; Chemical industry standards of the China; PN series (European system) in HG/T20592-20635-2009; Class series (American system) in HG/T20592-20635-2009.
