ASME B16.5 Flange Supplier in Sri Lanka

ASME B16.5 Flange Supplier in Sri Lanka, Weld Neck Flanges in Colombo (Sri Jayawardenepura Kotte) At Omaa Metal Sources, we deliver engineered flange solutions to meet the evolving demands of Sri Lanka’s oil & gas, chemical processing, and marine infrastructure sectors. Our extensive portfolio includes ASME B16.5, DIN, EN 1092-1, and API 6A flanges, built to handle high-pressure pipelines, aggressive media, and extreme temperature fluctuations. Whether it’s a hydrocarbon processing unit in Colombo, a thermal power plant in Trincomalee, or a shipyard in Galle, our flanges are tailored to the technical realities of each application. Our flange are available in a wide pressure class range from 150# to 2500# (PN6 to PN250), and sizes from 1/2” NB to 60” NB, making them suitable for everything from compact water lines to large-bore oil pipelines. We offer precision-manufactured flanges in a wide array of configurations including Weld Neck, RTJ, Socket Weld, and Lap Joint, optimized for reliable sealing and fatigue resistance under cyclic loading conditions. For severe service environments, our Ring Type Joint (RTJ) flanges are ideal for critical sealing applications. Material grades play a crucial role in flange performance. That’s why we offer a full spectrum—from ASTM A105 carbon steel for standard applications, to Duplex (F51) and Super Duplex (F53, F55) for chloride-rich environments like coastal and offshore installations. For chemical plants operating in corrosive atmospheres, we recommend Nickel Alloys such as Inconel 625 and Monel 400, all conforming to ASTM B564 and tested per ASTM A182. All our flanges are backed by MTCs, hydro tests, PMI, and ultrasonic inspection. Get a Quote.
