Flat welding flange with neck
Features:
The 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. Flat welding flange refers to a type of flange that is connected to a container or pipeline using a fillet weld. It belongs to any type of flange, and there are two types of flange rings: with and without a neck. Flat welded flanges have a simple structure and are made with fewer materials, but their rigidity and sealing performance are not as good as those of plain flanges. They are widely used for connecting medium and low pressure vessels and pipelines

Product Details
The neck height of the flat welded flange with a neck is relatively low, which improves the stiffness and load-bearing capacity of the flange. Compared with butt welded flanges, the welding workload is large, the consumption of welding rods is high, and it cannot withstand high temperature and pressure, repeated bending, and temperature fluctuations. However, on-site installation is more convenient, and the process of welding seam rubbing can be omitted.
The sealing surface forms include: raised face (RF), concave face (FM), raised face (M), tenon face (T), groove face (G), and full face (FF).
Diameter range: DN10~DN600.
Materials: carbon steel, chromium molybdenum steel, 304, 316, 304L, 316L, 321, 347, CF8C,etc.
Flat welding flanges with a neck are also classified as flat welding flanges because they have a short neck, which increases the strength of the flange and improves its load-bearing capacity. So it can be used on higher pressure pipelines.
The welding seam form between the neck flat welded flange pipe and the flange is a fillet weld. The material is machined from ordinary steel plates with a thickness that meets the requirements.
Application
Flat welded flanges are only suitable for pipeline systems with relatively low pressure levels and minimal pressure fluctuations, vibrations, and vibrations.
