Flanges are essential in piping systems that connect pipes, valves, pumps, and other equipment. They are circular discs with protruding rims that allow two pipes to be bolted together. Flanges are designed to withstand high pressure and temperature conditions, making them critical in applications such as oil and gas, chemical processing, and water treatment.
Flanges come in various materials, including carbon steel, stainless steel, and alloys. The most common flanges are weld neck, slip-on, socket weld, threaded, and blind flanges. In addition to these standard flange types, many specialized flanges are available. Some examples include orifice flanges, used to measure fluid flow, and reducing flanges, used to connect pipes of different sizes.
