ASTM A182 Grade F11 alloy steel lap joint flanges are designed for use in high-pressure and high-temperature piping systems where a bolted connection is required. These flanges are made from F11 alloy steel, known for its strength and resistance to elevated temperatures. The lap joint flange features a smooth, raised face that allows for a slip-on fit with a corresponding lap joint stub end, providing a reliable and leak-proof connection. This design is advantageous for systems where frequent disassembly and inspection are necessary. The lap joint flanges are machined to precise dimensions and are compatible with various pipe sizes and pressure classes. They are commonly used in industries such as petrochemical, chemical processing, and power generation.
