Flanges are flat, ring-shaped fittings that are used to connect pipes, valves, pumps, and other equipment in a piping system. Made from materials such as carbon steel, stainless steel, and alloy steel, flanges are used to form a strong, leak-proof joint. The main advantages of flanges are their ease of installation and their ability to create a secure, leak-resistant connection. Flanges come in a variety of types, such as weld neck, blind, slip-on, and threaded, to accommodate different piping systems and pressure levels. They are commonly used in oil and gas, water treatment, and chemical industries. Flanges are essential for ensuring the reliability and safety of high-pressure systems and are widely used in the construction and maintenance of industrial pipelines.
