ANSI socket weld flanges are manufactured to meet applicable ASME B16.5 requirements, covering flange dimensions, pressure-temperature ratings, materials, tolerances, and marking. Available in carbon steel, stainless steel, and alloy steel, they are designed for compatibility with industrial piping systems when the specified size, pressure class, and material meet project requirements.
Quality control focuses on raw material verification, dimensional accuracy, socket and weld-end quality, and surface inspection. These measures help ensure consistent product quality, reliable welded connections, and suitability for the intended piping application.
Oil and Gas Industry: Connecting small-bore piping in oil and gas processing systems.
Petrochemical Plants: Used in process piping for chemical and petrochemical facilities.
Power Generation: Suitable for auxiliary piping and industrial fluid systems.
Chemical Processing: Connecting pipes that handle compatible process fluids.
Industrial Piping Systems: Used in small-diameter pipelines requiring welded flange connections.
Water and Utility Systems: Applied in industrial water supply and utility piping.
