What Are Long Weld Neck Flanges
An extended neck that progressively shifts from the flange thickness to the pipe wall is known as a Long Weld Neck Flange (LWNF). Under high pressure, high temperature, and dynamic load situations, this design improves structural integrity and lessens the concentration of stress at the flange’s base. These flanges are generally utilized in sensitive applications, such as The long neck shape also facilitates perfect alignment during welding, ensuring minimal turbulence and pressure decrease in fluid flow systems. These flanges are perfect for high-pressure and high-temperature applications since they are frequently made from premium materials like stainless steel, carbon steel, alloy steel, and duplex steel.
