Flange connections involve securing two pipes, fittings, or equipment to separate flange discs first, then inserting a flange gasket between the two discs and bolting them together to complete the connection. Some fittings and equipment come with built-in flange discs and are also considered 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, flange connections are prevalent throughout the pipeline and equipment.
The types of flange connections, categorized by their connection methods, include: flat welding flanges, socket welding flanges, blind flanges, threaded flanges, flange covers, loose fit socket welding flanges with neck, flat welding loose fit flanges, ring groove flanges, and flange covers, large diameter flat flanges, large diameter high-neck flanges, ganged blank flanges, and socket welding loose fit flanges.
