Forged Flanges
For essential pipe-to-pipe connectivity in a wide range of industries, Forged Flanges from Fortis Forge are recognized for their exceptional strength, dimensional precision, and superior resistance to pressure, corrosion, and mechanical stress. These flanges are precision-engineered through advanced forging techniques to meet stringent performance and durability standards as per ASTM A105, ASME B16.5, and applicable DIN specifications. Manufactured using high-grade carbon steel or mild steel, our forged flanges offer excellent mechanical properties and are suitable for both low-pressure and high-pressure piping applications.
With advanced forging, CNC machining, heat treatment, and rigorous quality checks, Fortis Forge Forged Flanges ensure excellent sealing integrity and structural reliability in demanding industrial environments. Forging enhances the grain structure of the material, improving strength, fatigue resistance, and durability, making these flanges highly reliable for critical operations. They are commonly used in oil & gas, petrochemicals, power generation, refineries, shipbuilding, and water treatment industries.
We offer a wide range of forged flange types including:
Slip On Flanges (SORF)
Socket Weld Flanges (SWRF)
Weld Neck Flanges (WNRF)
Blind Flanges (BLRF)
Threaded/Socket Weld Flanges
Lap Joint Flanges
Ring Type Joint (RTJ) Flanges
Available in various sizes, pressure classes (Class 150 to Class 2500), and facing types (Raised Face, Flat Face, RTJ), our forged flanges provide safe, reliable, and cost-effective solutions for fluid handling and pipeline integrity in critical industrial applications.

What is a Forged Flange?
A Forged Flange is a high-strength pipe connection component used to join pipes, valves, pumps, and other equipment in a piping system. Forging enhances the mechanical properties of the metal, resulting in superior strength, durability, and leak-proof performance.
Forged flanges are available in multiple types to suit different industrial needs:
Weld Neck Flange – Ideal for high-pressure, high-temperature applications
Slip-On Flange – Easy to install, used for low-pressure pipelines
Socket Weld Flange – Suitable for small pipe diameters and high-pressure systems
Blind Flange – Used to close pipe ends or nozzles
Threaded Flange – No welding required; used in low-pressure, non-critical systems
Lap Joint Flange – Used with stub ends where frequent dismantling is required
Material Grades We Use
At Fortis Forge, our forged flanges are manufactured using:
Carbon Steel (ASTM A105)
→ High strength and durability under elevated temperatures and pressures. Commonly used in refineries, power plants, and oil & gas systems.
Mild Steel (IS 2062)
→ Offers cost-effective performance with good weldability and workability. Preferred for structural and general industrial piping.
Every flange is forged and finished to ensure:
High dimensional accuracy
Uniform grain structure
Leak-tight sealing surface
Resistance to stress, corrosion, and impact
