Which fastener type is most commonly used in piping systems?

Explanation:
Piping joints rely on fasteners that provide a strong, removable clamp and a reliable seal between flange faces. Threaded bolts do this by passing through the flange holes and being tightened with nuts, compressing a gasket to create a leak-tight joint. This setup handles internal pressure, temperature changes, and vibration, and it allows disassembly for maintenance or replacement. Nails and staples are designed for wood and don’t offer the necessary load-carrying capacity, corrosion resistance, or sealing ability. Pins may help with alignment, but they don’t provide the continuous clamping force needed to maintain a pressure-tight flange joint.
