Long Weld Neck Flanges (LWN Flanges) are forged pressure-containing components widely used in oil, gas, petrochemical, and refinery pipeline systems where high pressure and temperature resistance are critical. The extended tapered neck provides exceptional structural support at the butt-weld joint, reducing stress concentration and making them ideal for severe service conditions. These flanges conform to ASME B16.5 and ANSI standards, available in sizes from 1/2" to 48" in carbon steel, stainless steel 304/316, and alloy grades, making them a staple in global industrial equipment procurement and project supply chains.
