Application and analysis of weld neck flange in mechanical design

Weld Neck Flange are disc parts, flanges are used in pairs, and are most common in piping engineering. In pipeline engineering, Weld Neck Flanges are mainly used for pipeline connection. In the pipeline to be connected, a variety of installation of a flange, low-pressure pipeline can use wire flange, more than 4 kg of pressure using weld neck Flange.

　　Pumps and valves, in connection with the pipeline, these equipment parts, also made corresponding weld neck flange shape, also known as flange connection. All the connecting parts, which are closed at the same time with the bolt connection in the two plane, are generally called "flanges", such as the connection of the ventilation pipes, which can be called "flanged parts". But this connection is only a part of the equipment, such as weld neck flange and pump connection, it is not good to call the pump "flange parts". Smaller ones, such as valves, can be called "flange parts".

　　In pipeline engineering, weld neck flange are mainly used for pipeline connection. In the pipeline to be connected, a variety of installation of a flange, low-pressure pipeline can use wire flange, more than 4 kg of pressure using ASME B16.5 A182 Stainless Steel Weld Neck Flange. Seal the two flanges together and tighten them with bolts. Flange with different pressure has different thickness and different bolts.
