3" Flange

3" Flange is a standard pipe fitting used in petroleum, chemical and pipeline systems, suitable for medium and high pressure conditions.

Dimensional Standards: Manufactured strictly according to ASME B16.5 / EN / DIN standards, ensuring high consistency in hole spacing, thickness, and sealing surface dimensions.

Reliable Sealing Performance: The sealing surfaces (RF / FF / RTJ) are precision-machined with controllable surface roughness, effectively forming a stable seal with the gasket.

High Strength: The dense overall structure provides excellent tensile and impact resistance, making it suitable for applications with frequent pressure fluctuations.

Oil and Gas Pipelines: Provides reliable connections between pipelines and valves under medium and high pressure transmission conditions.

Chemical Plant Systems: Offers stable sealing connections under corrosive or high-temperature media conditions.

Power and Energy Engineering: Standardized connections between equipment and pipelines in pressure pipelines.

Industrial Fluid Transportation Systems: Pipeline connections and fixation for media such as water, steam, and oil.

Forging or Precision Casting: Improves material density

CNC Machining: Ensures accuracy in hole spacing, thickness, and sealing surfaces

Sealing Surface Finishing: Controls surface roughness and improves gasket sealing reliability

Dimensional and Pressure Inspection: Performs dimensional and quality inspections before shipment.
