A flange is a rib used to attach a pipe to another object, such as a flange on the end of a pipe or steam cylinder. Pipes and tubes can be easily assembled or disassembled using flanges, which can also fit onto different items, including bellows, wheels and cameras. Depending on the different designs, flanges can be further categorized into weld neck flanges, slip on weld flanges, threaded flanges, socket weld flanges, orifice flanges, blind flanges, and more. They are also classified by the raw material used to manufacture the flange, including carbon steel, alloy steel, stainless steel, high yield steel (line pipe flanges), and low temperature steel.
