Leading Supplier of ANSI B16.5 Flanges to
Brazil’s Oil, Gas & Petrochemical Sector
Werner Flanges is a certified manufacturer and exporter of ANSI B16.5 flanges to Brazil, supplying the full range of pressure classes, flange types, and material grades demanded by Brazilian industry. With over two decades of manufacturing expertise and a deep understanding of the Brazilian market, Werner Flanges delivers precision-engineered flanges to Petrobras-operated refineries, Braskem petrochemical complexes, power generation facilities, and infrastructure projects across the country.
Brazil is South America’s largest economy and one of the hemisphere’s most significant industrial markets. The country’s oil and gas sector — anchored by Petrobras’ expansive pre-salt operations in the Santos and Campos basins — drives exceptional demand for high-integrity piping components. Werner Flanges meets this demand by supplying ANSI B16.5 flanges compliant with ASME, ASTM, API, and NACE standards to major cities and industrial hubs including São Paulo, Rio de Janeiro, Campinas, Cubatão, Salvador, Recife, Belo Horizonte, and Manaus.
Our ANSI B16.5 product range covers all seven standard flange types in carbon steel, stainless steel, alloy steel, duplex, super duplex, and nickel alloys. Pressure classes from 150# through 2500# are available in sizes from 1/2” to 24” (with B16.47 coverage extending to 60”). Whether your application involves offshore floating production units, onshore refinery piping, pre-salt subsea infrastructure, ethylene cracker columns, or hydroelectric power plant cooling systems, Werner Flanges supplies the right product, certified and tested, with full documentation.
From our manufacturing facility, flanges destined for Brazil typically arrive at the Port of Santos or the Port of Rio de Janeiro within 18–25 days via sea freight, with expedited air freight options available for urgent requirements.
