ASME B16.5 300 WNRF Flange – Weld-neck flanges Manufacturer & Supplier
The ASME B16.5 300 WNRF (Weld Neck Raised Face) Flange is a medium-pressure component that handles 300 PSI applications. It is widely used in industries that require secure and leak-proof connections, such as refineries, chemical plants, and oil & gas pipelines. This Flange’s raised face (RF) design enhances gasket sealing, ensuring optimal performance under varying pressure and temperature conditions.

Overview of ASME B16.5 300 WNRF Flange
ASME B16.5 is a standard developed by the American Society of Mechanical Engineers (ASME), defining the specifications for pipe flanges and flanged fittings ranging from ½” to 24″ in nominal pipe sizes. The Class 300 Weld Neck Raised Face (WNRF) Flange is designed for applications requiring moderate pressure handling, offering a durable and high-integrity joint connection.
- Weld Neck Design: Provides superior strength and stress distribution, reducing fatigue and failure risks.
- Raised Face (RF) Configuration: Improves gasket sealing, preventing leaks in critical applications.
- Medium-Pressure Rating: With a pressure rating of 300 PSI, it is suitable for moderate pressure and temperature applications.
- High Durability: Made from carbon steel, stainless steel, and alloy steel, ensuring resistance to corrosion and wear.
- ASME Compliance: Designed to meet ASME B16.5 standards, ensuring compatibility and reliability in piping systems.
