Flanges

Flanges are mechanical connectors used to join pipes, valves, pumps, and other equipment within a piping system. They play a vital role in providing easy access for cleaning, inspection, or modification of the pipeline. Flanges come in various types such as weld neck, slip-on, blind, socket weld, and threaded, each suited for specific applications and pressure ratings. Typically manufactured from carbon steel, stainless steel, and high-performance alloys, flanges are designed to meet international standards like ASME, DIN, EN, and others for reliable and leak-proof connections.
