High Neck Flange Yellow Paint
A high neck flange refers to a higher neck height, which improves the stiffness and load-bearing capacity of the flange.
High neck flange: Compared with butt welding flange, the welding workload is large, the electrode consumption is high, and it cannot withstand high temperature and high pressure and repeated bending and temperature fluctuations, but the on-site installation is more convenient, and the process of welding seam film flaw detection can be omitted, which is more popular.
Manufacturing standards: HG/T20615-2009, ASME B 16.5
Connection method: flange nut, bolt connection
Production process: professional overall forging, forging manufacturing, etc
Processing method: high-precision CNC lathe turning, ordinary lathe fine turning, argon arc welding and other processing
Applications: boiler pressure vessel, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbow food and other industries
The full identify of neck welding flange is neck welding metal pipe flange, additionally recognized as excessive neck flange, English name: Slip-on, abbreviated as WN.
The neck flat welding flange, like the plate flat welding flange, is additionally a flange that extends metal pipes, pipe fittings, etc. into the flange and connects it to tools or pipelines via fillet welds.
The sealing floor varieties of neck flat welding flanges include: raised face (RF), concave face (FM), convex face (M), tenon face (T), groove face (G), and full face (FF).
Diameter vary of neck flat welding flange: DN10~DN600
Scope of application: PN collection PN2.5~PN40; Class sequence Class150~Class1500
Flange material: carbon steel, molybdenum steel, 304, 316, 304L, 316L, 321, 347, CF8C.
The manufacturing procedure is normally forging.
Advantages: Flat welding flanges with a neck are additionally labeled as flat welding flanges, as they have a brief neck, which improves the energy of the flange and improves its load-bearing capacity. So it can be used on greater strain pipelines.
Disadvantages: Compared to plate kind flat welding flanges, they have a greater price and are extra susceptible to collision at some point of transportation due to their form characteristics.
