Weld Neck Flange (WN Flange) is a high-pressure pipeline connecting component with a long tapered hub, designed to be butt-welded to pipes. It provides excellent reinforcement, high strength, and strong sealing performance, widely used in oil & gas, petrochemical, refinery, power plant, and long-distance pipeline projects. It effectively reduces stress concentration and improves fatigue resistance under high temperature, high pressure, and harsh working conditions.
