Long Weld Neck Flanges in Machilipatnam

Hi-Tech Exotic Alloys is a trusted Long Weld Neck Flanges manufacturer in Machilipatnam, offering high-quality Long Weld Neck Flanges for high-pressure piping systems, pressure vessels, heat exchangers, process equipment, and demanding industrial applications. We manufacture and supply Long Weld Neck Flanges in various materials, grades, sizes, pressure classes, facing types, and dimensions according to applicable ASTM/ASME standards, customer drawings, and project specifications.

Long Weld Neck Flanges (LWN Flanges) feature an extended neck or hub that provides a gradual transition from the flange to the pipe or equipment connection. Their longer hub can be useful in applications requiring additional reinforcement, alignment, or a longer welded connection. They are commonly used in high-pressure and high-temperature systems when specified by the engineering design.

Hi-Tech Exotic Alloys serves customers across oil and gas, refineries, petrochemical, chemical processing, power generation, pressure vessels, heat exchangers, and general engineering industries.
