Industrial Flange Exporter and Supplier in Singapore – ASME B16.5 Weld Neck, Slip-On, Blind, Lap Joint, Socket Weld, and RTJ flanges.
Omaa Metal Sources is a prominent supplier of premium-grade industrial flanges to Singapore’s highly advanced industrial and marine sectors, including shipbuilding in Jurong, chemical plants in Tuas, and refineries in Pulau Bukom and Jurong Island. We deliver flanges engineered for critical applications, conforming to ASME, DIN, EN, JIS, and API standards, ensuring integration across international pipeline systems.
We offer a wide spectrum of flanges from 1/2″ to 60″ NB, with pressure ratings up to 2500# (PN6 to PN250). Designed for Singapore’s tropical climate, our flange range includes Weld Neck, Slip-On, Blind, Lap Joint, Socket Weld, and RTJ flanges, manufactured for high resistance to corrosion, pressure surges, and thermal cycling. Our duplex and super duplex offerings (F51, F53, F55) are ideal for the offshore, petrochemical, and desalination industries.
Each flange undergoes stringent testing procedures, including PMI, ultrasonic testing, and hydrostatic examination. With full traceability and certifications like EN 10204 3.1/3.2, our flanges meet material standards such as ASTM A182 F304/316, A350 LF2, A694 F52 to F70, A105, and ASTM B564 (Nickel Alloys). We also supply Titanium, Alloy Steel, and Copper-Nickel flanges, ensuring material compatibility for aggressive media and critical applications. Get a Quote.
