Leading Flanges Manufacturer & Exporter to Brazil
Werner Flanges is a trusted international manufacturer and exporter of industrial flanges to Brazil, delivering premium-quality forged and machined flanges that meet the demanding requirements of South America's largest economy. Brazil's expansive oil and gas sector centered on Petrobras offshore pre-salt fields, its world-scale petrochemical complexes in São Paulo and Bahia, its prolific mining operations across Minas Gerais and Pará, and its growing infrastructure and water treatment networks together create sustained demand for precision-engineered piping components — and Werner Flanges is equipped to supply them all.
We supply carbon steel, stainless steel, alloy steel, and duplex flanges to industrial customers across Brazil’s major economic hubs: São Paulo, Rio de Janeiro, Belo Horizonte, Salvador, Porto Alegre, Curitiba, Manaus, and the critical deepwater oil and gas corridor linking Santos Basin to the port city of Santos. Our flanges are manufactured to internationally recognized standards including ASME B16.5, ASME B16.47, ASTM A105, ASTM A182, and ASTM A350, fully compatible with Petrobras procurement specifications (Normas Petrobras — N-xxxx series) and Brazilian national standards governed by ABNT (Associação Brasileira de Normas Técnicas).
As a direct manufacturer, Werner Flanges offers Brazil-based buyers significant cost advantages by eliminating intermediary trading layers — a major consideration in a market where import tariffs (typically 12–18% under Brazil’s Tarifa Externa Comum), ICMS, PIS/COFINS, and logistics costs must all be optimized for competitive landed pricing. Our comprehensive export documentation — including commercial invoices, packing lists, certificates of origin, and EN 10204 3.1 Material Test Certificates — ensures smooth customs clearance through the Port of Santos, Port of Rio de Janeiro, or Port of Itajaí, Brazil’s three primary import gateways for industrial goods.
Delivery to Brazil via sea freight from our manufacturing facility typically ranges from 25–35 days to Santos or Rio de Janeiro ports, with expedited air freight options available for urgent operational requirements. From major seaports, our logistics partners provide inland delivery by truck to industrial clients in São Paulo, Belo Horizonte, Campinas, and other interior destinations.
Whether you're procuring flanges for Petrobras deepwater riser systems in the Santos Basin, for Braskem polyethylene production units in Triunfo (Rio Grande do Sul), for Vale's iron ore beneficiation plants in Carajás, or for municipal water and wastewater infrastructure serving Brazil's rapidly urbanizing population, Werner Flanges delivers the technical quality, certification depth, and supply chain reliability that Brazilian industrial buyers demand

Industries and Applications We Supply
| Industry | Applications |
|---|---|
Oil & Gas |
Petrobras operates Brazil’s most extensive oil and gas infrastructure, encompassing offshore FPSOs in the Santos and Campos basins, onshore gathering networks, the REPLAN refinery in Paulínia (Brazil’s largest, 400,000 bpd), REDUC in Duque de Caxias (Rio de Janeiro), REPAR in Araucária (Paraná), and the Abreu e Lima refinery (RNEST) in Pernambuco. Each refinery consumes thousands of flanges annually across atmospheric and vacuum distillation units, fluid catalytic cracking (FCC), hydrocracking, hydrodesulfurization, and product blending systems.
For FPSOs operating in ultra-deepwater pre-salt fields, Werner Flanges supplies super duplex and Inconel flanges for topside process equipment handling CO₂-rich production fluids, as well as carbon steel and alloy steel flanges for utility systems, firewater, and accommodation modules. Subsea trees and manifolds require ASME Class 900# through 2500# flanges in corrosion-resistant alloys, meeting Petrobras’s stringent N-2162, N-2634, and N-2631 material specifications. |
Mining —and Nickel Processing: |
Vale’s Carajás S11D iron ore mine in Pará — the world’s largest iron ore mine — produces 90 million tons per year, with ore transported via the 892 km Carajás Railway to the Ponta da Madeira marine terminal. Ore processing and slurry pipeline systems require flanges resistant to abrasion and scaling, typically carbon steel in Class 150# and 300# ratings with wear-resistant internal liners. Werner Flanges supplies large-diameter Class 150# slip-on and weld neck flanges for slurry pump connections and pipeline manifolds.
Gold, nickel, and copper mining operations in Pará, Minas Gerais, and Goiás utilize flanges in flotation circuits, leaching systems, and acid plant process piping. Hydrometallurgical processes often require stainless steel or high-alloy flanges compatible with dilute sulfuric acid and chloride-bearing process streams. |
Petrochemicals |
Braskem’s Camaçari complex in Bahia — one of the largest integrated petrochemical complexes in the Americas — houses ethylene crackers, polyethylene and polypropylene units, PVC production, chlor-alkali facilities, and aromatics production. Werner Flanges supplies ASME B16.5 carbon steel Class 300# and 600# weld neck and slip-on flanges for ethylene and propylene distribution headers, stainless steel 316L flanges for corrosive chemical service, and alloy F11/F22 flanges for high-temperature cracking furnace connections.
Brazil’s white chemical, agrochemical, and pharmaceutical sectors, concentrated in São Paulo state, require small-to-medium diameter stainless steel flanges meeting hygienic or ASME BPE standards for API active pharmaceutical ingredient production and food-grade processing, a growing specialty market served by Werner Flanges’ precision-machined 316L product range |
Infrastructure & Water Treatment: |
Brazil’s Federal Law 14.026/2020 (New Sanitation Framework) mandates universal water and sewage service by 2033, driving an estimated R$700 billion in investment over the coming decade. State water utilities (SABESP in São Paulo, CEDAE in Rio de Janeiro, COPASA in Minas Gerais) and private concessionaires (Aegea, Iguá, BRK Ambiental) are procuring flanges for new water treatment plants, sewage treatment facilities, pumping stations, and transmission mains on an unprecedented scale. Werner Flanges supplies Class 150# carbon steel slip-on and weld neck flanges for pump connections, isolation valve interfaces, and pressure-reducing station piping throughout this infrastructure buildout. |
