Top 10 Flange Suppliers in China

Introduction to Flanges

Flanges are crucial components in piping systems. They are flat, circular discs with holes around the perimeter 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 system. They are available in various types, such as weld - neck flanges, slip - on flanges, blind flanges, and socket - weld flanges, and are made from different materials including carbon steel, stainless steel, alloy steel, and cast iron. The choice of flange type and material depends on factors like the pressure, temperature, and nature of the fluid flowing through the piping system.
