The Welding Neck Flange (WN Flange) is a crucial component in piping systems, designed for high-pressure applications across various industries. Manufactured by ZheJiang XILIQI Technology Co., Ltd., these flanges are known for their durability, precision, and versatility. The Welding Neck Flange features a long tapered hub that smoothly transitions into the pipe, providing reinforcement and reducing stress concentration. This design makes it ideal for applications involving extreme temperatures, high pressures, and sudden changes in system pressure. The Welding Neck Flange's structure allows for full penetration welding, ensuring a strong, integral connection with the piping system.
