Alloy steel and carbon steel Welding Neck Flanges are high-strength pipe fittings used to connect pipes, valves, pumps, and other equipment in industrial piping systems. Their welding neck design ensures a smooth, strong connection and excellent stress distribution — ideal for high-pressure, high-temperature, and critical service environments in petrochemical, oil & gas, power generation, and process industries.
