Mexico’s piping industry demands flanges that meet stringent international standards while withstanding the country’s diverse operating environments — offshore Gulf platforms, high-temperature refinery streams, chemical processing lines, and large-scale water infrastructure projects. Werner Flanges meets this demand through a comprehensive product range manufactured to ASME B16.5, ASME B16.47, DIN 2573/2576, and API specifications, covering all standard pressure classes from 150# through 2500# and sizes from ½” to 60″.

Our slip-on flanges are available in carbon steel (ASTM A105, A350 LF2), stainless steel (A182 F304/L, F316/L, F321), alloy steel (F11, F22, F91), duplex and super duplex (F51, F53, F55), and high-nickel alloys including Inconel and Monel — giving Mexican procurement teams a single, trusted source for every project requirement. Every flange is manufactured in our ISO 9001:2015-certified facility using closed-die forging, CNC precision machining, and third-party inspected material test certificates, ensuring full traceability from heat to installation.

We ship directly to Mexico's primary import ports — Veracruz, Altamira-Tampico, and Manzanillo — with standard sea freight transit times of 18–25 days from our works, and accelerated air freight options to Mexico City's Benito Juárez International Airport when project schedules demand it. Our technical sales team provides 24-hour quotation turnaround, Spanish-language documentation support, and dedicated project management for large-volume orders.

Industries and Applications We Supply

Industry	Applications
Oil & Gas Industry	Mexico produces approximately 1.48 million barrels of oil per day (2024), with offshore production concentrated in the shallow and deepwater blocks of the Gulf of Mexico — the Cantarell complex, the Ku-Maloob-Zaap fields, and newer developments at Zama and Trion. Pemex’s onshore production is centred in Tabasco and Veracruz, with significant midstream infrastructure connecting to refineries at Salina Cruz (Oaxaca), Minatitlán (Veracruz), Cadereyta (Nuevo León), Salamanca (Guanajuato), Tula (Hidalgo), and the new Dos Bocas refinery in Tabasco.Slip-on flanges from Werner Flanges are used throughout these systems: on upstream wellhead and gathering piping (carbon steel, 600#–1500#), midstream pipeline connections (A105, 150#–300#), refinery process lines (carbon and alloy steel, various classes), and downstream product distribution (SS 316L for product quality lines). Our A350 LF2 low-temperature slip-on flanges are specified for LNG satellite stations and cryogenic service on the Gulf Coast.
Petrochemical & Chemical Processing	The Coatzacoalcos–Minatitlán corridor in Veracruz is Mexico’s primary petrochemical complex, home to Pemex Petrochemical’s facilities as well as Braskem Idesa’s ethylene cracker and polyethylene plants. The complex processes natural gas liquids, methanol, and aromatics — demanding slip-on flanges in stainless steel (A182 F316L), alloy steel (F11, F22), and duplex (F51) for corrosive process streams. Additional chemical clusters in San Luis Potosí, Monterrey (Nuevo León), and the State of Mexico generate further demand for high-specification flanges.
Power Generation	Comisión Federal de Electricidad (CFE) operates Mexico’s national electricity grid through a mix of combined-cycle gas turbine plants (which account for ~55% of generation), hydroelectric stations, coal-fired units at Carbón II (Coahuila), and geothermal plants in Michoacán and Baja California. Slip-on flanges are critical in boiler feed-water systems, steam turbine connections, cooling water pipework, and condensate return systems. Carbon steel A105 flanges at 300#–600# and alloy steel F22 flanges at 900# class are the most common requirements.
Water & Wastewater Treatment	Mexico’s northern states face significant water scarcity, driving investment in municipal water infrastructure, wastewater treatment plants, and industrial water reuse systems. The National Water Commission (CONAGUA) is managing major pipeline rehabilitation projects, while industrial zones in Monterrey, Chihuahua, and Tijuana require robust flanged connections for cooling tower circuits and process water distribution. Flat-face carbon steel slip-on flanges at 150# class are the workhorse solution for these systems.

Frequently Asked Questions (FAQs)

q1: are your slip-on flanges compliant with pemex procurement standards?: yes. werner flanges’ slip-on flanges are manufactured to asme b16.5 and astm material standards, which are the specifications referenced in pemex exploration and production and pemex industrial transformation procurement specifications. we provide en 10204 3.1 mtcs, dimensional inspection reports, and third-party inspection options (tÜv, dnv, bv) to satisfy pemex supplier quality requirements.
q2: what is the typical delivery time to mexico?: standard sea freight delivery to the port of veracruz or port of altamira is 18–25 days from our manufacturing facility. air freight to mexico city’s aicm, monterrey’s gdl, or guadalajara airports takes 5–7 days. ex-works and cif pricing to mexican ports is available. for urgent requirements, we maintain a ready stock of standard-size slip-on flanges in carbon steel (a105) and stainless steel (f304l/316l) that can be despatched within 48–72 hours.
q3: can you supply nace mr0175-compliant flanges for sour gas service in the gulf of mexico?: yes. we supply slip-on flanges fully compliant with nace mr0175 / iso 15156 for hydrogen sulphide (h₂s) sour-service environments. this includes carbon steel a105 flanges with controlled hardness (≤ 22 hrc), duplex f51 and super duplex f53/f55 grades, and nickel alloy options. nace compliance documentation is provided with each shipment.
q4: do you offer custom bore sizes or non-standard specifications?: yes. werner flanges has full custom manufacturing capability. we can machine slip-on flanges to non-standard bore diameters (matching specific pipe wall thickness schedules), supply specialty facing configurations, produce flanges with extra-thick hubs, or manufacture to din, bs, or customer-specific engineering standards. please provide your project specification or data sheet and we will provide a detailed technical and commercial proposal within 24–48 hours.
q5: can you supply large-diameter slip-on flanges above 24″ for pipeline projects?: yes. for diameters above 24″ (dn600), we manufacture to asme b16.47 series a (equivalent to mss sp-44) and series b (equivalent to api 605). these large-bore flanges are forged in carbon steel (a105), stainless steel (a182 f304/316), and duplex grades to custom sizes up to 60″ diameter. they are widely used in mexico’s cross-country transmission pipelines, lng storage facilities, and large-bore petrochemical process lines.
q6: what ndt testing is available and can a mexican buyer’s inspector witness it?: we offer a full range of non-destructive testing at our works: magnetic particle inspection (mpi), liquid penetrant inspection (lpi), ultrasonic testing (ut), and radiographic testing (rt). buyer’s inspectors and nominated third-party inspection agencies (tÜv, dnv, bv, lloyd’s, sgs) are welcome to attend testing at our facility. an inspection & test plan (itp) is issued prior to manufacture for all inspection-witnessed orders.
q7: do you provide technical support for material selection?: yes. our technical sales team can assist with material grade selection based on your process fluid, temperature, pressure, and corrosion environment. we provide written material recommendations for challenging applications — including sour gas, chloride-containing streams, cryogenic service, and high-temperature duties — and can supply asme b16.5 pressure-temperature rating calculations upon request.
