Necked flat welding flange

Overview:

The full name of the necked flat welding flange is the necked flat welding steel pipe flange. It is a flange in which steel pipes, pipe fittings, etc. are inserted into the flange and connected to equipment or pipelines through fillet welds. The necked flat welding flange has a short neck, which is connected to the flange plate. The function of the neck is to increase the rigidity and strength of the flange, enabling it to better withstand the pressure and stress of the pipeline. At the same time, it also helps to reduce stress concentration at the connection between the flange and the pipeline.
