Long Weld Neck Flanges are designed for high-pressure and high-temperature applications where added support and reinforcement are essential. Featuring an extended neck, these flanges provide smooth transition from flange thickness to pipe or vessel wall, reducing stress concentration. Commonly used in pressure vessels, storage tanks, and critical piping systems, they are ideal for applications requiring extra neck length for stability and strength. Long Weld Neck Flanges ensure secure, leak-proof connections in demanding industries such as oil & gas, petrochemical, and power generation, offering superior performance, alignment, and long-term reliability in challenging environments.
