Class 150 Flanges Suppliers in the Philippines, ASME B16.5, B16.47 Series A/B, DIN, EN 1092-1, and API 6A standard in Manila
Omaa Metal Sources is a globally recognized manufacturer and exporter of high-quality industrial flanges, catering to the evolving needs of the Philippines’ oil & gas, petrochemical, marine, and power generation sectors. From Manila and Cebu to Davao, Quezon City, and Batangas, our flanges are used in critical flow control systems across diverse industrial projects.
We supply flanges with pressure ratings from 150# to 2500# and PN6 to PN250, conforming to ASME B16.5, B16.47 Series A/B, DIN, EN 1092-1, and API 6A standards. The size range starts from ½” NB up to 60” NB, and we provide tailor-made flange solutions for special project specifications. Whether for offshore rigs in Palawan or geothermal plants in Leyte, our flanges offer long-term sealing reliability and superior fatigue resistance.
Our product line includes forged and machined flanges made from carbon steel (ASTM A105, A350 LF2), stainless steel (304/316 series), high-yield steel (A694 F52–F70), and exotic alloys like Inconel, Monel, Hastelloy, and Duplex/Super Duplex (F51, F53, F55). These meet or exceed international standards such as ASTM A182, ASTM B564, and ASTM B381, and are supplied with complete traceability, including MTCs, NDT reports, and third-party inspections.
