Industries and Applications We Supply

Industry	Applications
Oil & Gas Industry	Mexico’s oil and gas sector is dominated by PEMEX (Petróleos Mexicanos), which produces approximately 1.48 million barrels per day and has committed to an active 2025–2030 investment plan targeting 18 new fields, 15 new offshore platforms, and continued development of the Ku-Maloob-Zaap, Ayatsil-Tekel, and Zama fields in the Gulf of Mexico. This sustained capital program creates consistent, long-term demand for certified pipeline flanges across upstream, midstream, and downstream operations.Upstream: Weld neck flanges serve wellhead equipment, production manifolds, test separators, and flowline piping on PEMEX’s onshore fields in Tabasco and Chiapas and offshore platforms in the Campeche Sound. RTJ weld neck flanges in Class 1500# and 2500# are standard for wellhead Christmas tree connections and subsurface safety valve installations.Midstream: PEMEX’s national pipeline network relies on A105 carbon steel weld neck flanges in Class 150# through 600# for pipeline isolation valves, launcher/receiver connections, pig trap flanges, pump station piping, and metering station manifolds linking Veracruz, Tampico, Salamanca, Reynosa, and the northern border zone.Downstream / Refinery: PEMEX operates six refineries — Salamanca (Guanajuato), Tula (Hidalgo), Salina Cruz (Oaxaca), Cadereyta (Nuevo León), Minatitlán (Veracruz), and the new Olmeca (Dos Bocas) refinery in Tabasco — the centrepiece $12 billion downstream investment of the current administration. All six facilities require weld neck flanges in crude distillation units (CDU), vacuum distillation, hydrotreating (HDT), fluid catalytic cracking (FCC), and reforming units, with F11 and F22 alloy steel for high-temperature hydrogen service and F316/F316L stainless for corrosive overhead systems.
Petrochemical & Chemical Processing	The Coatzacoalcos-Minatitlán corridor in Veracruz is one of Latin America’s most concentrated petrochemical zones. Braskem Idesa — Mexico’s largest petrochemical complex, producing 1 million tonnes of polyethylene annually — alongside PEMEX Petroquímica units and multinational chemical producers depend on weld neck flanges throughout their ethylene crackers, polyethylene and polypropylene units, vinyl chloride monomer (VCM) trains, and chlorinated hydrocarbon handling systems. F316L and duplex F51 weld neck flanges in Class 600# and 900# are the dominant specification for corrosive service in this complex.
Power Generation	Comisión Federal de Electricidad (CFE) operates Mexico’s national power grid with over 85 GW of installed capacity spanning thermal, combined-cycle gas turbine (CCGT), hydroelectric, geothermal, nuclear (Laguna Verde, Veracruz), and wind generation. CFE’s modern CCGT plants specify F22 and F91 alloy steel weld neck flanges for high-pressure steam main piping. The Laguna Verde nuclear station additionally requires nuclear-grade documentation packages for non-safety system piping. Werner Flanges supplies CFE-formatted material certification packages for all relevant applications
Water & Wastewater Treatment	Mexico’s National Water Commission (CONAGUA) and municipal water authorities operate extensive treatment and distribution infrastructure serving 130+ million people. Carbon steel Class 150# weld neck flanges serve pump station headers, filter influent/effluent manifolds, and chlorination system piping. WNFF (flat face) flanges are standard where cast iron pump bodies are in service. Werner Flanges supplies AWWA C207 Class B and Class D flanges for large-diameter water mains serving Mexico City, Guadalajara, Monterrey, and secondary cities.

Frequently Asked Questions (FAQs)

q1: do werner flanges’ products meet pemex procurement specifications?: yes. werner flanges manufactures to asme b16.5 and asme b16.47 — the primary standards referenced in pemex procurement documentation — with full en 10204 type 3.1 material traceability. we assist with pemex vendor registration and provide product data sheets formatted for pemex document control.
q2: can you supply nace mr0175-compliant flanges for pemex’s sour service systems?: yes, and this is a standard offering. a105n carbon steel flanges are normalized to meet nace hardness limits (22 hrc max). f22 alloy steel flanges are produced with controlled pwht to nace f22 requirements. duplex and super duplex flanges are solution annealed, tested for microstructure and hardness. nace certificates are issued as part of the standard documentation package for all sour service orders.
q3: what is the typical lead time for weld neck flange orders to mexico?: standard items in common materials (a105, f316l) in class 150#–600# ship within 2–4 weeks ex-works. non-standard materials (f91, f53, inconel), larger sizes (nps 20″+), and class 900#–2500# typically require 4–8 weeks ex-works. sea freight to major mexican ports is 18–25 days. rush orders with air freight are available for critical shutdowns or maintenance emergencies.
q4: can werner flanges match flanges to existing piping at our refinery without providing asme tables?: yes. provide size, pressure class, material, and pipe schedule (or od/wt) and our engineering team will confirm all asme b16.5 dimensions. we can also reverse-engineer from sample measurements for critical replacements of worn or damaged flanges.
q5: can you supply large-diameter weld neck flanges above 24″ for pemex pipeline projects?: yes. sizes above nps 24″ are manufactured to asme b16.47 series a (mss sp-44) and series b (api 605) for pemex trunk pipeline isolation valve stations and compressor station tie-ins. lead times for large-diameter flanges are 6–12 weeks ex-works; contact us early in your project cycle.
q6: do you provide spanish-language documentation for pemex/cfe project requirements?: our standard documentation is in english, the accepted engineering language for asme and api standards in mexico. commercial documents (invoices, packing lists, certificates of origin) can be provided bilingually or in spanish on request.
q7: are werner flanges products approved for use in mexico?: mexico does not operate a single mandatory national product approval scheme for industrial flanges. products must conform to the engineering standards (asme b16.5, astm material specs) specified in the project or pemex/cfe procurement documents. werner flanges’ complete documentation package — en 10204 3.1 mtc, dimensional inspection, pmi, ndt, and third-party inspection — meets all evidentiary requirements for pemex and cfe project approval.
