Long Welding Neck Flanges (LWN Flanges) are specially designed flanges featuring an extended tapered hub (neck), which provides a smooth transition of stress from the flange to the connected pipe or vessel.
They are primarily used in high-pressure, high-temperature, and critical service applications, especially in pressure vessels, columns, and reactor systems. The long neck acts as a reinforcement, improving strength and reducing stress concentration at the connection point.
