Flange connections involve fixing two pipes, fittings, or equipment to separate flange plates first, then adding a flange gasket between the two plates and securing them together with bolts to complete the connection. Some fittings and equipment come with a flange plate already attached, which also falls under flange connections. Flange connections are an important method of pipe construction. They are convenient to use and can withstand high pressure. In industrial pipelines and residential settings, where pipe diameters are small and pressure is low, flange connections are not visible. However, in boiler rooms or production sites, flange connections are ubiquitous on pipes and equipment.
Flange connections can be categorized by their connection methods as follows: flat焊接flanges, welding neck flanges, socket welding flanges, slip-on flanges, threaded flanges, flange covers, welding neck ring-type loose flanges, flat ring-type loose flanges, ring groove flanges and flange covers, large diameter flat flanges, large diameter high neck flanges, winged blind flanges, and socket welding ring-type loose flanges, etc.
