EN grooved flange two-piece is a critical connection for piping systems, designed to combine the reliable sealing of a flange with the quick installation advantages of a grooved connection. The fitting consists of two flanges bolted together with an integrated internal groove structure that allows direct snap-on connection to grooved pipes or valves for fire protection, water supply and drainage, industrial piping and other scenarios. Its flexible material selection, compatibility with European (EN) and North American (ASME) standards, and support for high-pressure, high-temperature environments, while simplifying on-site installation and maintenance processes, make it an ideal choice for modern modular piping systems.
