Flanges are essential components in piping systems, connecting pipes, valves, and other equipment. These circular discs with raised edges facilitate easy assembly and disassembly, ensuring a secure and leak-free connection. Typically made from materials like carbon steel or stainless steel, flanges come in various types, including slip-on, weld neck, and blind flanges, each serving specific purposes. The choice of flange depends on factors like pressure, temperature, and the nature of the fluid being transported.
