Introduction to Pipe Flanges
Pipe flanges are crucial components in piping systems. They are flat, circular discs with holes that are used to connect pipes, valves, pumps, and other equipment to form a piping network. Flanges provide easy access for cleaning, inspection, and modification of the piping system. They can be made from a variety of materials such as carbon steel, stainless steel, alloy steel, and cast iron, and come in different types including weld - neck flanges, slip - on flanges, socket - weld flanges, blind flanges, and lap - joint flanges. The quality and performance of pipe flanges directly affect the safety and efficiency of the entire piping system.
