Weld Neck

Carbon Steel Weld Neck Flanges are engineered for high-pressure and high-temperature piping systems where strength, durability, and leak-resistant performance are essential. Featuring a tapered hub that provides smooth stress distribution, weld neck flanges are ideal for critical applications in industrial, commercial, and process piping. Commonly used in oil and gas, chemical processing, power generation, water treatment, and manufacturing, these flanges are available in a variety of sizes, pressure classes, and schedules to meet ANSI/ASME standards.
