Transmission Flange Forgings | High-Strength Components
At Weforging, we manufacture custom forged flanges designed for strength, precision, and durability. Using carbon steel, alloy steel, and stainless steel, our flange forgings meet demanding industrial requirements. We supply global OEMs in oil & gas, petrochemical, marine, power generation, construction, and heavy machinery sectors. Each flange is hot forged or cold forged, CNC machined, and inspected under international standards. This ensures long service life, reliable performance, and consistent quality in critical applications worldwide.
Flange Forging Capabilities
Weforging manufactures custom forged flanges using advanced hot forging, cold forging, rolled ring forging, and precision CNC machining to achieve high strength and dimensional accuracy.Our flange range covers multiple configurations — weld neck, slip-on, blind, socket weld, lap joint, threaded, and fully custom-designed options — suitable for various pressure classes and industrial systems.
We offer a wide selection of materials, including carbon steel (A105, 20Mn), alloy steel (42CrMo4, 34CrNiMo6), stainless steels (304, 316, 321), and heat-resistant alloys, with every flange produced according to ANSI, ASME, EN, DIN, JIS, and ISO standards for precision and reliability.
Precision Machining & Finishing
CNC Machining
Turning, boring, drilling, and facing operations ensure tight tolerances and smooth sealing surfaces for all forged components.Heat Treatment
Processes such as normalizing, quenching, and tempering are applied to improve hardness, toughness, and fatigue resistance.Inspection & Testing
Each part undergoes strict quality checks, including CMM verification, ultrasonic (UT), magnetic particle (MPI), hardness testing, and metallurgical analysis.Surface Finish Options
Customers can choose from precision machining, protective coatings, galvanization, or other finishes tailored to specific requirements.
These controlled machining and finishing processes guarantee smooth surfaces, reliable sealing, and long-term durability for demanding industrial environments.
Applications of Custom Flange Forgings
Weforging’s custom forged flanges are built for high-performance industries that demand strength, precision, and sealing reliability.With advanced forging and CNC machining, each flange ensures secure connections and consistent performance under high pressure, temperature, and corrosive conditions.
Main applications include:
Oil & Gas: High-pressure flanges for refineries, offshore platforms, and transmission systems.
Petrochemical: Alloy and stainless flanges for chemical and high-temperature environments.
