We offer our customers with cost-effective, reliable and high quality superior flanges. LWNRF flange is similar to neck weld flange but the ‘neck’ is longer and is used as a nozzle for a barrel. The two types are long weld neck heavy barrel and equal long weld neck barrel with different shapes.

ANSI / ASME B16.5 LWN Flanges are suitable for extreme temperature fluctuations and excessive handling and ending. They are also used in applications that involve high pressure and need for a hub that is long and tapered. It is required in vessels that need an extended neck or hub which acts as an extension. It helps to reduce the thickness of steel and used in chemical, petroleum industries, commercial and residential buildings which has high levels of stress and temperatures that fluctuate.
