Weld Neck Flanges are widely used in high-pressure and high-temperature applications. Their tapered hub design helps distribute stress evenly, reducing the risk of failure. Many Chinese flange factories manufacture weld neck flanges in carbon steel, stainless steel, and alloy steel for industries such as oil & gas, power generation, and chemical processing. With advanced forging and machining capabilities, modern pipe fitting factories can provide customized dimensions and materials to meet project requirements while ensuring long service life.
