What is the Primary Function of Long Weld Neck Flange?
The primary function of a Long Weld Neck flange is to act as an integral, self-reinforced stress-transition nozzle that disperses pressure-induced and thermal loads over a gradual taper, protects the critical sealing face from welding distortion, and extends the fatigue life of the connection—making it the preferred choice for severe, high-integrity corrosive services like those requiring Hastelloy C-276 (UNS N10276).
