Introduction to Flanges
A flange is a flat, circular disk with holes around its perimeter that is used to connect pipes, valves, pumps, and other equipment to form a piping system. Flanges provide easy access for cleaning, inspection, and modification of the system. They are available in a wide range of sizes, materials, and pressure ratings to meet different industrial requirements. Common materials for flanges include carbon steel, stainless steel, alloy steel, and cast iron. Flanges play a crucial role in various industries such as oil and gas, chemical, power generation, water treatment, and shipbuilding.
