What is the primary function of flanges in piping systems?

The primary function of flanges in piping systems is to connect pipes, valves, and other equipment securely. Flanges serve as mechanical joints that provide a reliable seal between two components, allowing for the transfer of fluids under pressure while minimizing the risk of leaks. These connections are essential for maintaining the integrity of the piping system, ensuring that fluid flows properly from one segment to another.

Flanges are designed to work under various pressures and temperatures, and they come in different shapes and materials to suit specific operational conditions. By bolting a flange to another flange or to a fitting, you achieve a robust connection that can be easily disassembled for maintenance or repair without cutting the pipe. This functionality is crucial in industrial applications where downtime needs to be minimized.

The other options, while related to piping systems, do not accurately describe the primary role of flanges. Flanges do not filter fluids, measure pressure, or store fluid; their main purpose is to provide a solid and effective connection between different pieces of piping or equipment to ensure the safe and efficient transport of materials.
