LONG WELD NECK FLANGE

1. What is a Long Weld Neck Flange

Long Neck Welding flanges (LWN) are similar to a standard Welding Neck flange, but the “Neck” is considerably longer. These Long Weld Neck Flange is often used as a nozzle for a barrel or column. In addition, there are the type LWN Heavy Barrel (HB) and the Equal LWN Barrel (E); they have a different shape and a thicker “Wall”.
