• 3″ Class 900, ASME B16.5, ASTM A105

• 4″ Class 900, ASME B16.5, ASTM A105

Weld Neck Flanges (RF)

• 3″ Class 900, SCH 80, ASME B16.5, ASTM A105

• 20″ Class 900, SCH 60, ASME B16.5, ASTM A105

• 12″ Class 300, SCH 40, ASME B16.5, ASTM A105

• 4″ Class 900, SCH 80, ASME B16.5, ASTM A105

All weld neck flanges are supplied with accurately machined bevel ends to ensure smooth welding and strong joint integrity.

Material and Performance Advantages

ASTM A105 carbon steel is widely used for pressure-containing components due to its excellent strength, toughness, and weldability.

Combined with ASME B16.5 dimensional control, these flanges are suitable for high-pressure and high-temperature service conditions.

The raised face (RF) design improves gasket sealing performance, making the flanges ideal for oil, gas, power, and general industrial piping systems.

Typical Applications

These ASME B16.5 A105 flanges are commonly applied in:

• Oil and gas processing facilities

• Petrochemical and refinery piping systems

• Power generation plants

• Industrial pressure pipelines

Quality Control and Inspection

Haihao Group implements strict quality assurance procedures throughout manufacturing, including:

• Raw material traceability and verification

• Dimensional inspection to ASME B16.5

• Visual and surface finish inspection

• Final inspection prior to shipment

Complete documentation is provided to ensure full compliance with project and international standard requirements.
