The flat welding flange is a widely used piping fitting designed to connect pipes, valves, or equipment in industrial and commercial systems. Its defining feature is a flat, circular disc with a central bore (matching the pipe’s inner diameter) and bolt holes around the perimeter, enabling secure, leak-resistant joints via welding.Its smooth sealing surface (FF) ensures leak-free operation in non-toxic, low-pressure applications such as municipal water networks, HVAC systems, and general industrial pipelines, while the reinforced concave-convex (MF) face enhances sealing integrity for slightly more demanding environments.
