Flange connections involve securing two pipes, fittings, or equipment to each side of a flange, inserting a flange gasket between them, and then bolting the two flanges together to complete the connection. Some fittings and equipment come with a built-in flange, which also falls under the category of flange connections. Flange connections are a crucial method in pipeline construction. They are convenient to use and can withstand high pressure. In industrial pipelines and residential settings, you might not see flange connections when the pipe diameter is small and the pressure is low. However, in boiler rooms or production sites, flanged pipes and equipment are everywhere.
According to the connection method, flange types can be categorized as: flat welding flange, neck welding flange, neck butt welding flange, socket welding flange, threaded flange, flange cover, neck butt welding ring loose flange, flat welding ring loose flange, ring groove flange and flange cover, large diameter flat flange, large diameter high neck flange, blind flange, butt welding ring loose flange, etc.
