Alloy steel threaded or screwed flanges are designed to provide a detachable connection for pipes, valves, and other equipment without the need for welding. They feature internal threads that allow them to be screwed onto corresponding threaded pipe ends or fittings, making them a versatile option for systems where welding is impractical or undesirable. These flanges are commonly made from high-strength alloy steels, such as ASTM A182 F11, F22, and A350 LF2, which offer excellent performance under high-pressure and high-temperature conditions. Threaded flanges are available in various pressure classes and sizes to meet different system requirements. Their design is advantageous for applications that require frequent disassembly or maintenance, as they facilitate easy connection and disconnection. They are typically used in industries such as oil and gas, chemical processing, and power generation.
