ANSI Flanges

ANSI Flanges

Our ANSI Flanges (American National Standards Institute) are manufactured to comply with ANSI/ASME B16.5 specifications, ensuring reliable and standardized connections for pipes, valves, and equipment in pressure-intensive applications. These flanges are widely used across industries such as oil & gas, petrochemical, power generation, marine, and water treatment. Available in pressure classes ranging from 150 to 2500, Metalok ANSI flanges are produced in various types—weld neck, slip-on, blind, socket weld, threaded, and lap joint—using premium materials like carbon steel, stainless steel (SS 304/316), and alloy steel.
