About Long Weld Neck Flange

The Long Weld Neck (LWN) Flange is a specialized flange designed for high-pressure and high-temperature applications. Unlike standard weld neck flanges, the LWN flange features an extended neck that acts as a nozzle for pressure vessels, tanks, and process piping systems. Manufactured in Carbon Steel, Stainless Steel, and Alloy Steel, Induskarts LWN flanges conform to ANSI B16.5 / ASME standards and are forged for superior strength, durability, and leak-proof performance.
