Alloy Steel Lap Joint Flanges are designed to be used in conjunction with a stub end, allowing the flange to rotate freely around the pipe. This design facilitates easy alignment during installation and is especially suitable for systems requiring frequent dismantling.
Manufactured from high-strength alloy steel, these flanges offer enhanced mechanical properties, including improved resistance to high temperature, pressure, and corrosion, making them ideal for demanding industrial environments.
