Industrial Flange Manufacturer for Mission-Critical Applications
MFC Flange manufactures forged flanges for industries where performance standards are non-negotiable and material failures are not an option. Operating out of our fully integrated facility in Sealy, Texas, we supply flanges and forgings globally to sectors ranging from petrochemical and oil and gas to power generation and chemical processing.
Our ISO 9001-certified facility gives engineers and procurement teams the documentation trail they need. Every flange we produce is manufactured to ANSI, ASME, ASTM, DIN EN, and PED standards, and our domestic manufacturing ensures full DFARS compliance for projects that require it.
We work with a broad inventory of 40 material types, including stainless steel, nickel alloys, duplex stainless steel, and chrome alloys, so we can match the right material to the specific demands of your application. If your project calls for a manufacturer with verified credentials and the capacity to scale, contact MFC Flange for a quote.
Oil and Gas Flanges for Upstream, Midstream, and Offshore Use
The oil and gas sector spans a wide range of operating conditions, from subsea environments to high-temperature refinery service. Flanges used in these applications must meet strict dimensional standards and withstand both mechanical stress and corrosive media.
Our duplex stainless steel flanges are particularly suited to offshore and subsea applications, where the combination of high strength and chloride corrosion resistance is a primary design concern. For topside and onshore applications, our commodity flange product line covers weld-neck, blind, slip-on, and orifice flange types, all manufactured to ASME B16.5 and B16.36 standards.
We understand that unplanned downtime in oil and gas operations carries significant cost. On-time delivery is a key metric we track across our entire operation, and we maintain expedited production processes to support time-sensitive project requirements.
Power Generation Flanges Rated for High-Temperature Service
Power generation systems, whether conventional or nuclear, operate under sustained high temperatures and pressures. Material selection is critical, and procurement teams in this sector typically require full documentation of mechanical properties and heat treatment records.
Our nickel alloy flanges are manufactured specifically for demanding thermal environments, offering high-temperature strength that standard austenitic grades cannot match. MFC Flange has a documented history of supplying the nuclear power and power generation industries, and our testing capabilities include tensile testing, Charpy impact testing, hardness testing (BHN), and full traceability through our ISO 9001 quality system.
For power generation projects requiring ASME or PED compliance, our certifications are available for review and can be provided as part of project documentation packages.
Flanges for Chemical Processing Requiring Material Verification
Chemical processing facilities handle a wide variety of aggressive media, and the consequences of selecting the wrong flange material are severe. Procurement engineers in this sector require documented evidence of material composition, not just a mill certificate.
MFC Flange performs in-house Positive Material Identification (PMI) on our products, giving customers verifiable confirmation that the material delivered matches the specification ordered. Our 300 Series stainless steel flanges are suited for applications involving water, moisture, and moderate chemical exposure, while our corrosion-grade nickel alloys address more aggressive service conditions.
Our machine shop produces flanges to precise dimensional specifications, and all chemical processing flanges are inspected against ANSI, ASME, and DIN EN standards before shipment. Explore our commodity flanges to review material grades and flange types available.
Why Project Managers and Engineers Specify MFC Flange
The practical question for any specifying engineer is whether a manufacturer can deliver the right material, to the right standard, on time, with the paperwork to back it up. Our facility in Sealy, Texas, is built around that requirement.
We operate as a fully integrated forging and machining facility, handling cutting, forging, machining, heat treatment, and testing under one roof. This gives us direct control over quality at every stage and eliminates the delays and traceability gaps that come from outsourcing steps in the process. Our heat treatment capabilities, including solution heat treatment, annealing, and water quenching, are performed on-site and documented within our ISO 9001 quality management system.
For projects requiring domestic supply chain compliance, our inventory is 100% DFARS compliant, and we are fully aligned with AIS and BABA requirements for federally funded infrastructure work. Whether your requirement is a bulk run or a small urgent order, reach out to our team to discuss what we can provide.

Our flanges are commonly used in industries like offshore drilling and nuclear power – industries where standards for performance, safety, and accuracy are extremely high. That’s why MFC Flange holds ourselves to rigorous standards on every product we manufacture.
Frequently Asked Questions
What flange materials are suitable for sour service in oil and gas applications?
Sour service environments — those containing hydrogen sulfide (H2S) — require flanges that comply with NACE MR0175/ISO 15156. Materials such as specific grades of duplex stainless steel and certain nickel alloys can meet these requirements when manufactured and tested to the applicable standard. The correct material selection depends on the partial pressure of H2S, the temperature, and the chloride content of the process fluid. We recommend consulting with your project metallurgist and confirming that the material grade and heat treatment meet NACE requirements before specifying. MFC Flange can provide documentation to support this review.
What is the difference between ASME B16.5 and B16.47 flanges, and which does MFC supply?
ASME B16.5 covers flanges in sizes from ½ inch through 24 inches, across pressure classes from 150 to 2500. ASME B16.47 covers large-diameter flanges from 26 inches through 60 inches in pressure classes 75, 150, 300, 400, 600, and 900. MFC Flange manufactures to ASME B16.5 and B16.36 standards. If your project requires B16.47 flanges, we recommend confirming size and class requirements with our team directly so we can advise on what we can supply or accommodate.
Do you provide material test reports (MTRs) with your flanges?
Yes. As an ISO 9001-certified manufacturer, our quality system supports full material traceability from raw materials through finished products. Our outsourced partners add testing capabilities, including chemical analysis, tensile testing, and PMI, generate the documentation needed to support MTR requirements.
