Introduction to Flange
A flange is a ring or collar, usually with holes for bolts, used to connect pipes, valves, pumps, and other equipment to form a piping system. It provides a convenient way to assemble, disassemble, and maintain the system. Flanges come in various types, such as weld - neck flanges, slip - on flanges, blind flanges, and socket - weld flanges, and are made from different materials including carbon steel, stainless steel, alloy steel, and non - ferrous metals. They play a crucial role in many industries like oil and gas, chemical, power generation, and water treatment.
