Which pipes typically require flanged joints for their assembly?

Larger industrial pipes typically require flanged joints for their assembly due to their size and the need for secure connections in high-pressure or high-temperature applications. Flanged joints provide a robust and reliable method of connecting pipes, allowing for ease of maintenance and disassembly when necessary. The flanges create a tight seal that can withstand significant pressure and stress, making them suitable for the demanding environments often found in industrial settings.

In contrast, low-pressure metal pipes may not need the same level of secure connection, while residential plumbing pipes usually utilize simpler methods such as solvent welding, compression fittings, or threaded connections to facilitate easier installation and repair. Flexible PVC pipes are designed for different applications and are commonly connected using slip fittings or other simpler methods that do not require flanged joints.
