Forged Flange Forgings — Strong, Reliable Pipe Connections
At Weforging, we manufacture high-strength flange forgings designed for performance, precision, and durability. Produced from carbon steel, alloy steel, and stainless steel, our flanges are available in weld neck, slip-on, blind, socket weld, and threaded designs. Each product is hot forged or cold forged, then CNC machined to achieve tight tolerances and smooth sealing surfaces. Trusted by OEMs across oil & gas pipelines, petrochemical plants, wind power, marine engineering, and heavy machinery, Weforging ensures every flange meets ISO 9001 standards with full testing and documentation. Our goal is to deliver reliable, custom flange solutions that optimize efficiency and reduce costs for global industries.
Materials & Flange Types
Weforging offers forged flanges in a wide range of materials, including A105 carbon steel, 20Mn, 42CrMo4 alloy steel, and stainless steel grades 304/316. These materials provide excellent strength, toughness, and corrosion resistance, making them suitable for pipelines, pressure vessels, and heavy machinery.
Our production covers all major flange types such as weld neck, blind, slip-on, threaded, and socket weld designs. Each flange can be hot forged, CNC machined, and heat treated to meet strict dimensional tolerances. We also provide custom flange forgings based on client drawings and industry standards, ensuring reliable performance in demanding oil & gas, petrochemical, marine, and energy applications.
Why Choose Our Flange Forgings?
Our flange forgings are applied in:
Oil & Gas pipelines – high-pressure joints ensuring safe and efficient transport.
