Superior Strength and Durability

Thanks to the forging, heat treatment, and machining process, WNRF Flanges 304 deliver excellent tensile strength (515 MPa min) and yield strength (205 MPa min). Their robust construction makes them suitable for high-pressure and high-temperature operations, ensuring long-lasting and secure piping connections in critical industrial environments.

Versatile Connection and Leak-Proof Design

Weld Neck Flanges 304 are engineered for welded connections, which provide exceptional integrity and prevent leaks. Their compatibility with various face types (RF, FF, RTJ) enhances their adaptability across different piping systems and applications, while the ring-shaped hub helps reduce stress concentration, prolonging the lifespan of both flange and piping.

Corrosion Resistance and High Purity

Fabricated from stainless steel 304 with 98% purity, these flanges offer outstanding resistance to corrosion and rust. This makes them ideal for harsh environments like oil & gas, petrochemical, and water treatment plants, safeguarding installations against contamination and chemical attack. Their polished and machined surfaces ensure easy maintenance and high cleanliness standards.

FAQs of Weld Neck Flanges (WNRF Flanges) 304:

Q: How are Weld Neck Flanges (WNRF Flanges) 304 typically installed in a piping system?

A: WNRF Flanges 304 are installed by welding the flange neck to the pipe, creating a smooth transition and minimizing stress at the base of the flange. This butt-weld connection ensures a strong, leak-proof joint suitable for high-pressure and high-temperature applications across various industries.

Q: What face types are available for WNRF Flanges 304 and how do they differ?

A: WNRF Flanges 304 are available in Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ). Raised Face enhances gasket sealing, Flat Face is used for matching with cast components or full-face gaskets, while RTJ is preferred for high-pressure, critical applications needing metallic ring gaskets.

Q: When should you use a Weld Neck Flange 304 instead of other flange types?

A: Weld Neck Flanges 304 are ideal when high strength, leak-proof connections, and the ability to withstand wide temperature and pressure ranges (from -196C to 800C and up to 2500#) are necessary. They are commonly chosen for critical systems in oil, gas, petrochemical, and power generation sectors.

Q: Where can Weld Neck Flanges 304 be used most effectively?

A: These flanges are widely used in oil & gas pipelines, petrochemical plants, power stations, water treatment facilities, and general industrial systems where corrosion resistance, strength, and long-term reliability are essential. Their versatility makes them suitable for both above-ground and subterranean installations.

Q: What is the manufacturing process for WNRF Flanges 304?

A: WNRF Flanges 304 are manufactured via hot forging, followed by heat treatment and precise machining. This process improves strength and ductility, ensures standardized thickness (SCH10 to SCH160), and meets dimension and tolerance requirements set by ASME/ANSI/DIN standards.

Q: How does the corrosion resistance of Stainless Steel 304 benefit the longevity of weld neck flanges?

A: Stainless Steel 304s high chromium and nickel content provide outstanding resistance to corrosion and rust, ensuring a long service life in aggressive environments. This property reduces maintenance needs and protects piping systems from environmental and chemical damage.

Q: What advantages do Weld Neck Flanges 304 offer for high-pressure projects?

A: WNRF Flanges 304 are engineered to handle pressures from 150# to 2500# (PN6 to PN400), offering structural robustness, superior sealing, and safety in high-pressure, high-stress applications. This makes them a dependable choice for critical process piping and pressure vessel connections.
