Industries and Applications We Supply

Industry	Applications
Oil & Gas Industry	Brazil’s oil and gas sector — anchored by Petrobras’ USD 102 billion strategic investment plan — represents the largest market for stainless steel flanges in the country.Upstream (E&P): Pre-salt FPSO vessels operating in the Santos Basin (Búzios, Tupi fields) and Campos Basin require duplex and super duplex flanges for topside piping, seawater injection headers, and subsea production equipment. Extreme water depths (2,000–3,000 metres), high CO₂ partial pressures, and aggressive seawater conditions demand F51 and F53 grades as minimum specifications.Midstream (Transportation): Brazil’s gas pipeline network — including the GASBOL Bolivia–Brazil pipeline and TBG transport infrastructure — requires flanges at compressor stations, pigging manifolds, and block valves. F316L is specified where sour service or moisture is possible. Downstream (Refining): Petrobras’ 11 refineries — REPLAN (Paulínia, SP), REDUC (Duque de Caxias, RJ), RNEST (Ipojuca, PE), and REVAP (São José dos Campos, SP) — require stainless steel flanges for crude distillation, catalytic reforming, hydrogen service, and corrosive chemical handling units. F321 and F347 are specified for high-temperature service
Petrochemical & Chemical Processing	The Camaçari Petrochemical Complex in Bahia — the largest integrated petrochemical hub in the Southern Hemisphere — houses Braskem, BASF, Dow, and numerous specialty chemical manufacturers. F304L and F316L flanges are extensively used throughout ethylene crackers, polymerisation units, and chlor-alkali production lines. The Paulínia (REPLAN) cluster in São Paulo and the Suape Industrial Complex in Pernambuco are additional major procurement centres.
Power Generation	Brazil generates approximately 83% of its electricity from renewables — primarily hydro — with the remainder from gas, nuclear, biomass, wind, and solar. Werner Flanges supplies across all technologies: F316 stainless for cooling water systems at Itaipu, Belo Monte, and Tucuruí; F321/F347 for high-temperature steam systems at Angra I and Angra II nuclear plants; and F304 for steam generation at São Paulo’s ethanol mills — where Brazil produces more ethanol than any country except the USA.
Water & Wastewater Treatment	With rapid urbanisation across São Paulo (21M), Rio de Janeiro (12M), and Belo Horizonte (5M), demand for advanced water and wastewater infrastructure is growing significantly. F304 and F316 flanges serve municipal water treatment plants, pumping stations, and distribution networks. Coastal cities including Fortaleza, Recife, and Salvador are investing in seawater desalination where F316L and duplex F51 provide the necessary chloride resistance.

Frequently Asked Questions (FAQs)

q1: what grades do you supply for brazil’s pre-salt offshore fields?: for deepwater pre-salt environments — with high co₂ partial pressures, chloride-rich seawater, and elevated pressures — werner flanges supplies duplex f51 (uns s31803) and super duplex f53 (uns s32750). both are provided with full nace mr0175-compliant documentation for sour service specifications.
q2: do your products comply with petrobras procurement standards?: yes. our flanges conform to asme b16.5, astm a182, and nace mr0175 — the primary standards referenced by petrobras and anp. third-party inspection by bv, tüv, or dnv is available to meet petrobras vendor qualification requirements.
q3: what are the lead times to brazil?: standard grades (f304, f316, f316l) are typically available in 2–3 weeks. duplex and super duplex grades require 3–5 weeks manufacturing time. sea freight to santos or rio adds 18–24 days; air freight delivers in 3–5 days.
q4: can you supply din or bs standard flanges for legacy brazilian projects?: yes — werner flanges manufactures to din 2631–2638 and bs 4504, relevant for brazilian projects with european engineering heritage or historical plant specifications.
q5: what documentation is needed for brazilian customs?: standard requirements include commercial invoice, packing list, certificate of origin, bill of lading, and material test certificates — all provided as standard. additional siscomex-compatible documentation support is available on request.
q6: can you apply custom project marking for petrobras or braskem projects?: yes. customer-specific heat numbers, project codes, colour coding, and supplementary marking per client specifications can all be applied. all flanges are permanently marked per mss sp-25 as minimum, with full batch-level traceability.
q7: is pmi testing available?: yes — pmi via xrf analysis is standard for duplex and super duplex grades, and available on request for all stainless grades. reports are included in the documentation package.
