What is the primary purpose of a flanged connection in pipefitting?

The primary purpose of a flanged connection in pipefitting is to secure two pieces of pipe for easy maintenance. Flanged connections consist of two flanges bolted together, which allows for a removable and adjustable joint. This design not only makes it easier to assemble and disassemble pipes but also enables quick access for maintenance, repairs, or inspections without the need for cutting or welding the pipes. This flexibility is essential in systems where frequent maintenance is critical or where modifications might be needed over time.

While other options mention rigid connections or permanent joints, these do not reflect the fundamental advantage of flanged connections, which is their suitability for maintenance purposes. The choice emphasizing maintenance captures the core function of flanged connections in practical applications.
