Flange

Flanges are important piping components used to connect pipes, valves, pumps and other equipment in a piping system. They provide a convenient and secure connection method for assembly, maintenance, inspection and replacement. Flanges are widely used in fire protection systems, water treatment plants, municipal water supply networks and industrial piping projects. We supply a wide range of flanges in different types, sizes, pressure classes, materials and standards to meet various project requirements and international market needs.
