Introduction to Flanges
A flange is a flat, circular disk or ring with holes drilled around its perimeter. It is used to connect pipes, valves, pumps, and other equipment to form a piping system. Flanges provide a way to create a leak - tight joint, allowing for easy assembly, disassembly, and maintenance of the system. They come in various sizes, materials (such as carbon steel, stainless steel, alloy steel, etc.), and pressure ratings to meet different industrial requirements. Flanges are widely used in industries like oil and gas, chemical, power generation, water treatment, and many others.
