Labdhi Metals is a well-established manufacturer, stockist, and exporter of superior-quality Alloy 20 Flanges, recognized for their exceptional resistance to corrosion in highly aggressive environments. Alloy 20, also known as Carpenter 20 or UNS N08020, is a nickel-iron-chromium austenitic alloy specifically engineered to withstand sulfuric acid corrosion, as well as chloride-induced pitting and stress corrosion cracking. These properties make Alloy 20 flanges ideal for use in industries such as chemical processing, petrochemicals, pharmaceuticals, food and beverage, and power generation.
Labdhi Metals manufactures a wide range of Alloy 20 flanges, including Weld Neck (WNRF), Slip-On (SORF), Blind (BLRF), Socket Weld, Lap Joint, Threaded, and Ring Type Joint (RTJ) flanges. These flanges are fabricated using premium quality raw materials and cutting-edge forging and machining technologies, ensuring excellent dimensional accuracy, structural integrity, and surface finish. The flanges are designed to operate efficiently under high pressure and temperature conditions while offering superior sealing capability.
As a trusted stockist, Labdhi Metals maintains a robust inventory of Alloy 20 flanges in various sizes ranging from ½” NB to 24” NB, and pressure ratings from 150# to 2500#, ensuring immediate availability for urgent and large-scale industrial projects. These flanges are available in different facing types such as Raised Face (RF), Flat Face (FF), and RTJ, and can be customized as per specific project requirements. The flanges meet international dimensional standards and are suitable for use in both seamless and welded piping systems.
Labdhi Metals is a leading exporter of Alloy 20 flanges, supplying to markets across North America, Europe, Asia-Pacific, Gulf countries, and Africa. All products are manufactured in compliance with international standards such as ASTM B462, ASME B16.5, ASME B16.47, and EN 1092-1, and are supplied with complete Material Test Certificates (MTCs), third-party inspection reports, and full traceability documentation. Every flange undergoes strict quality checks such as PMI testing, ultrasonic inspection, and hydrostatic testing.
