Forged Flanges
Regnum Precision Pvt Ltd manufactures in-house forging of flanges which are designed to seamlessly connect sections of pipe or joint pipes to pressure vessels, valves, pumps, or any other integral flange assembly. These critical components provide robust access for cleaning, inspection, and system modifications.
We manufacture a comprehensive range of high-pressure forged pipe fittings and flanges for process control, instrumentation, hydraulic, and pneumatic applications. Our precision-engineered flanges meet the general and critical needs of the Oil & Gas, Petrochemical, Chemical Fertilizer, Steel Plant, Offshore, and Power Generating Industries.

Types of Forged Flanges
Explore our comprehensive range of flange configurations designed for specialized pressure and routing requirements.
Weld Neck / Long Weld Neck
Designed to transfer stress to the pipe, reducing high-stress concentration at the base of the flange. Ideal for severe, high-pressure environments.
Slip-On Flange
Slips over the pipe and is welded both inside and outside to provide sufficient strength and prevent leakage. Excellent for lower pressure systems.
Blind / Spectacle Blind
Used to seal the end of a piping system or pressure vessel opening to prevent flow. Spectacle blinds allow for flow isolation during maintenance.
Lap Joint Flange
Used in conjunction with a stub end, allowing the flange to rotate for easy alignment of bolt holes. Highly utilized in systems requiring frequent dismantling.
Threaded Flange
Can be attached to the pipe without welding. Best suited for small diameter, low-pressure applications, and highly explosive areas where welding is hazardous.
Orifice Flange
Specialized flanges used in combination with orifice meters for measuring the flow rate of liquids or gases through a pipeline system.
Key Applications
Heavy Duty Industrial
Heavily relied upon for robust industrial applications requiring high-pressure load capacity and leak-free joint integrity.
Power Plants
Critical structural connectors utilized in massive power generation facilities to handle thermal expansion and extreme operational stress.
Oil Refinery
Engineered to safely connect heavy duty piping modules in volatile petrochemical and oil refinery environments.
Construction of Pipelines
The primary bolting mechanism used during the vast construction of cross-country transport pipelines.
