A flange connection is the process of fixing two pipes, fittings, or equipment onto a flange. A flange gasket is added between the two flanges, which are then bolted together to complete the connection. Some pipe fittings and equipment already come with flanges, which also belong to flange connections.
Flange connection is an important connection method in pipeline construction. The flange connection is convenient to use and can withstand large pressures.
In industrial pipelines, flange connections are widely used. In households, the diameter of the pipeline is small and it is low-pressure, so flange connections are not visible. If in a boiler room or production site, there are pipes and equipment connected by flanges everywhere.
According to the connection method, flange connection types can be divided into: plate type flat welding flange, neck flat welding flange, neck butt welding flange, socket welding flange, threaded flange, flange cover, neck butt welding ring loose sleeve flange, flat welding ring loose sleeve flange, groove face flange and flange cover, large diameter flat flange, large diameter high neck flange
