FLANGES
FLANGES
Our range of industrial flanges is manufactured to meet stringent quality standards and withstand the toughest operating conditions across sectors such as oil & gas, petrochemical, power, water treatment, and process industries. Designed for strength, durability, and leak-proof connections, our flanges are available in various types including weld neck, slip-on, socket weld, blind, lap joint, and threaded flanges. We offer a wide range of sizes, pressure ratings (ANSI, DIN, JIS, and other international standards), and material grades such as carbon steel, stainless steel (SS304/SS316), duplex, super duplex, Monel, Inconel, and other specialty alloys. Every flange is precision-machined and quality tested to ensure tight sealing, corrosion resistance, and compatibility with high-pressure, high-temperature systems. Whether you’re assembling piping systems, pressure vessels, or instrumentation setups, Metalok Industries flanges ensure secure, long-lasting connections that meet the demands of modern industrial operations.
