Introduction to Steel Flange
Steel 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. Steel flanges provide a way to create a leak – tight joint, allowing for easy assembly and disassembly of the piping system for maintenance or modification. They come in various types, such as weld – neck flanges, slip – on flanges, blind flanges, and socket – weld flanges, and are made from different grades of steel to meet diverse industrial requirements, including high – pressure and high – temperature applications in industries like oil and gas, chemical, power generation, and water treatment.
