Introduction to Pipe Flange
Pipe flanges are crucial components in piping systems. They are flat, circular discs with holes drilled around the perimeter to allow bolts to pass through, which are used to connect pipes, valves, pumps, and other equipment to form a piping network. Pipe flanges provide easy access for cleaning, inspection, and modification of the piping system. They come in various types, such as weld - neck flanges, slip - on flanges, blind flanges, and socket - weld flanges, each with its own specific application scenarios. The materials used for pipe flanges include carbon steel, stainless steel, alloy steel, and others, depending on the requirements of the fluid being transported, pressure, and temperature conditions.
