ASEME B16.5 ASTM A694 / ASME SA694 F42 Carbon Steel Flange Weld Neck / WNRTJ Flange

 

 

The ASTM A694 F42 WNRTJ Flange is a robust, mission-critical component for high-pressure piping networks. Its combination of a strong welding neck, reliable metal-sealing RTJ face, and grade F42 carbon steel makes it the preferred choice for demanding upstream, midstream, and downstream applications where safety, durability, and leak-tight performance are non-negotiable. Manufactured from ASTM A694 Grade F42 steel with a minimum yield strength of 42 ksi (290 MPa), this flange is engineered specifically for high-pressure, high-temperature transmission service in demanding industries. When bolted, the RTJ groove compresses the metal ring gasket to create a durable, leak-tight metal-to-metal seal, making it a critical component in oil & gas wellheads, pipeline manifolds, and petrochemical reactor connections.

High-Pressure Service Capabilities

  • Pressure Ratings: Available in Class 600, 900, 1500, and 2500 (ASME B16.5 / ASME B16.47).

  • Temperature Range: Suitable for cryogenic to elevated temperatures (typically -46°C to +350°C, depending on material heat treatment).

  • Bolt Connection: Designed to withstand high bolt preloads without gasket blowout, making it ideal for HP/HT (High-Pressure/High-Temperature) wells, pipelines, and manifold systems.

 

 

Applications

  • Oil & Gas Exploration: Wellhead connectors, Christmas trees, choke manifolds.

  • Pipelines: High-pressure transmission lines, compressor stations, and metering skids.

  • Chemical/Petrochemical: Reactor nozzles, heat exchanger connections, and high-pressure steam lines.

  • Hydrogen & Sour Service: With appropriate NACE MR0175/ISO 15156 compliance for H₂S environments.
