Valve End Connection Types: Flanged, Threaded, Socket Weld, Butt Weld, Wafer and Lug
Learn how to choose valve end connection types including flanged, threaded, socket weld, butt weld, wafer, lug, clamp and grooved connections by pressure, size, maintenance, welding, installation and project requirements.
How to Choose Valve End Connection Type: NPT vs Flanged vs Socket Weld
Compare NPT, flanged, and socket-weld valve connections by pipe size, pressure and temperature capability, leak tightness, installation cost, maintenance access, and application. NPT connections suit small, low-pressure water and air lines; flanged ends allow easier removal and servicing in medium- to large-size industrial pipelines; socket-weld connections provide permanent, leak-resistant joints for small-bore, high-pressure, and high-temperature systems.
